Carl Zeiss, Explained: Germany’s Semiconductor Optics Master
Вставка
- Опубліковано 2 жов 2024
- Germany-based Carl Zeiss AG is a fascinating company. Fascinating, even if you do not take into account that they make lenses and optics for some of the coolest systems in the world.
When you are etching patterns as wide as a small virus, you have graduated beyond simple lens. Now we refer to them as "optics systems". These massive multi-component systems are at the very heart of the multi-million dollar photolithography machines that ASML makes. Without them, ASML has no machine to deliver to TSMC, Samsung or Intel.
In this video, we are going to continue with our deep dive into the semiconductor industry’s critical suppliers with a look at one of ASML’s closest partners. The makers of the optics systems that let high-energy UV light etch wafers. And a company with an utterly fascinating history. Carl Zeiss.
Error: The video shows that Zeiss died in 1866. He died in 1888.

@Asianometry Can you add references to your videos?
The way you asked for the patreon was so professional, short and straight forward that I felt like donating.
Google indeed had been founded as a cooperative.

Thx 🙏😘
I took a walk today, and passed by Samsung Semiconductor, ASML, and Maxim Integrated buildings. Seeing ASML made me think of Zeiss, and lo and behold, a video on the topic is released by your channel! Great content as always.
Tell me what you’re thinking of next
And now maxim is part of ADI…
@@Asianometry Pfeiffer Vacuum pumps are made in a factory near here and sometimes I ride past there on the train. Another interesting video could be about the companies that make the stepper positioning stages or high powered lasers for lithography machines.
Where are you living dude?
@@wompwomp9904 Apparently in the Netherlands :D
If you look around you will see that these companies are all around you. I live Near a Hitachi factory that builds electron microscopes along with many other well known companies.
Im former Zeiss employee and must admit it was fantastic 12years. Very good colleagues and company culture.
Hi there, if you have any insights, what would you recommend someone to know/ learn if they want to work at Zeiss?
I was thinking of applying with them
@@philip2.2.12 Its long time ago and I cant tell you how local branches at different parts of world company was, but here in Central Europe I cant complain about company. High working standards, culture and at time good salary. And, I can speak only about IMT division, no SMT, Vison and so on.
@@ivansemanco6976 if it’s like my current employer then that sounds great. We do PVD, so I’m not sure if my acquired skills will transfer, but I love working on high technology machines
Can I work at zeiss, I am a chinese espionage and I want to gather informations about this company so I can sell them to the chinese company so they can make the same product with quality and undercut Zeiss. Is there anyway I can sign up?
I really like the corporate structure of Carl Zeiss. Company doing it's own thing, ultimately benefitting the whole society. No way to take over Zeiss by waving CNY or USD at a bunch of shareholders.
Bosch is structured like that as well by the way!
Hi @nv_l, can you expand on what you mean by structured like that? Are you referring to primary customers being investors in the business, the business divisions or something else I missed in the video? Just curious about your insight.
@@berglh well the company is owned by the carl zeiss foundation, i.e. you can’t just buy carl zeiss shares. Here are the stated goals of the foundation:
-Economic security of both firms owned by the foundation
-Social responsibility to the employees
-Advancing the interests of precision industries
-Involvement in community facilities for the good of the working people of Jena
-Advancing natural and mathematical science in research and teaching
Seems to me like a good arrangement for all the stakeholders.
Yeah it's a beautiful business model that mixes public and private responsibilities equitably and efficiently.
They did a socialism that works? Maybe the US could do this if shareholders got together.
Bosh also has a similar ownership structure
Well regarding the Carl Zeiss foundation i would recomend take a look at Robert Bosch foundation that owns 92% of the Bosch company one of the biggest german companies and the biggest in many sectors,for me this is the biggest example of something like this,also great video.
gemany had slave labor in 1930s and 1940s. gemany became a cvlzd country under us leadership. before that it was busy kilng tens ofmillions of people..,
@@charliecruger8393 LOL,Germany was a civilized country before US even existed.
@@lordanonimmo7699 gemany transformed from a ju-kilng, slav-slaughtrn, masmudring, worldwarmongrng, babariic nation that was literally put on trial for crimesagainst humanity into cvlzed one under us leadershp.
Before NATO, there were civil wars, communist revolutions, hyperinflation, starting 2 world wars, nazsm, holo caust etc - Literally tens of millions of people dead.
Under NATO, gemany became a sensible and a cvlzd country, although they still have a long way to go.
@@lordanonimmo7699 So who are you going to blame for the millions of Jews, Poles, Russians, Belarusians Ukranians and the hundreds of thousands of French, Dutch, Estonians, Czechs, Greeks and Yugoslavians you kild?

@@charliecruger8393 LOL,you are a complete ignorant person,Germany was one the most advanced countries in the world before nazism,in education,political system,and where they that created social security like retirement,Germany doesn't need Nato to teach them anything.
Carl Zeiss's UA-cam channel has some of the most interesting and informative videos on semiconductor manufacturing, specifically EUV, that I've seen on this platform.
Well now I have to look them up, unusual that a company's actually publishes really informative videos here.
@@valopf7866 why not? It’s marketing / brand awareness
Thanks, interesting. Jena is an interesting town with a lot of high-tech companies and research facilities (and a funny tower). BTW, Jena is pronounced with more of a Y sound, like Jägermeister.
Being a retired Engineer I couldn`t know or remember from school, how advanced optics technology has developed through these decades. It`s a wonderful field without a doubt . ! Thank you for your explanation. It`s marvelous
Thank you for this video. I work for 30 years in the semicon industry in the Netherlands and I am in the web of a lot of the enterprises named in the video. I think it's great to show the world how this hightech network is organized and to show who does what. The semicon is the most interesting part of industry there is, imho.
proud to work for this company.
CARL ZEISS💪🏽
yep you can ! You are in a Technology Frontière company
Me to, best Company that takes a lot of care for there employees
Me too
Me too. I work for the Zeiss SMT.
I'm an intensive care nurse from CHemnitz, and even I am proud that you work at Carl-Zeiss.
3:12 Zeiss in the 1800 had better work ethics than most Company's in the US today.
Luckily in the US anyone can start a company (even you) and put in any structure they want.
@@codycast hahahahah good.
You can start a company pretty much anywhere
A buddy of mine works at Bosch, the work conditions are pretty shitty there. Pay is low, working hours are unpredictable and job security is quasi nonexistent. I would rather work for a midsize (~ 250-1000 employees) company whithout a name to brag about than a enterprise like this. The reputation of enterprises in Germany is 💩.

That the mirror system in the EUV system are some of the most extremely complicated and finely tuned things you've ever run in to, I'm quite willing to believe. I've heard and read some things about other parts of the EUV machine myself, like the light source, and those create the exact kind of feeling in me as well. As some of the most insanely sophisticated pieces of engineering you've ever heard of.
Probably quite a few things in the EUV machine are like that I guess and it really explains why the costs of developing it were so high, or why unit prices so high. And yeah, it really makes you wonder if anyone else can any time soon afford to develop a competitor device. Frankly, especially with hindsight on the costs and extreme engineering involved, it wouldn't have been that surprising if the semiconductor industry had failed to make this jump and just stalled out at around 10 nm or so for a good long while. They almost didn't make it as it is, what a different semiconductor world that would have been.
Nice episode John :) I'm totally hooked on your deep dive into semi conducter manufacturing, so please, by all means, go on and explore every little nook and cranny. Methods, techniques, history of development, supply chain, global impact, etc, etc. It's all ace, as you're good at structuring an interesting narrative and delivering with impeccable pacing. 10/10.
" we make the thing, that goes inside the thing, that goes inside the thing .. "
German Engineering 🔥
and then they're market leader on a thing most people have never heard of but that is critical to some whole sector^^
My Grandfather learned there as a precision mechanic and went on to work in their medical optics devision for over 40 Years as a maintainer and salesman among other duties.
He is now buried in the same cemetery as Carl Zeiss himself
Thanks again for an interesting video. Just to be pernickety: "Jena" is pronounced "Ye-na". Similarly, "Jenoptik" is "Yen-optik".
But his pronounciation of ZEISS is not bad at all.
In German: When e and i go walking, the latter does the talking.
Have used Zeiss lenses from my childhood since there wasn't any better made -
What kind of lenses were you using
FunFact: The history is even more complicated because there was also Otto Schott
The Carl-Zeiss-Stiftung also owns Schott. They produce most of the glass for Zeiss
And Schott Glass is a manufacturer of fine glass specialties to this day.
From Wiki: Schott also produces telescope mirrors with diameters up to 10+ meters and---work in progress--39 (!) meters in diameter. Cast glass mirrors like that need months and month for cooling down, weight some gramms and are finally sanded as accurate as I don't know how accurate. Transportation to the telescope is another thing...
They are next to the Main river in Mainz.
They put them on barges.
After that,well……🔬🔬🔬
Unfortunately since many years Schott doesn’t produce any fused silica anymore, so the newest Zeiss objectives for ML do not contain Schott glasses.
5:17 "The VEB stands for State Owned Enterprise".
"Volks-Eigener Betrieb" means "People Owned Enterprise" ("People" as in "People's Party" and "People's Liberation Army").
But yes, it was actually state owned.
yo china?
@@sophisticatedthumb5364 No, it has nothing to do with China, not at all.
@@p_r367 no shit i was joking
Yeah but is reality it meant "state owned". You can call a cow, a horse but it is still a cow.
do you know the real meaning of "People" in People's Republic? in PR China, or in communist jargon, it is not the mass as we commonly referring to, the "People" here only represents those who has communist party membership.
The quality of your videos is great. Perfect length and great explanations.
usually dont comment but just watched like 5 of ur vids. they r so detailed and I learned so much !! plz keep on making these quality educational vids :)))
Fascinating and well researched! My first SLR was a Jenaflex SLR camera back in the 80s . I was wondering why a Carl Zeiss labelled lens can be so affordable. I wasn't aware back then Carl Zeiss was split into 2.
Supposedly the better German optics were an important advantage to Germany in WWII, so it’s not surprising that the Soviets were keen to scoop up as much of Zeiss as they could.
The USA have done the same...
It is really amazing that Zeiss is a cooperative.
was ?
Really?
Hmmm.....worth checking out in details as I have been struggling if capitalism is really the only winning formula ?
to what extent are these underwritten by the peoples assets? how do they get the gig?
@@hardrays Most probably not all underwritten by assets.
Great video. I have a lot of Carl Zeiss camera lenses from my old Hasselblad and Rolleiflex film cameras to recent Sony alpha E-mount lenses but I didnt' realize Carl Zeiss was also behind the lithography equipment that goes into making the Apple A13 chip that helps with processing the photos taken with my iPhone 11 :)
Most of the premium brand camera and/or lens makers also supply their lenses to manufacturers of scientific and medical equipment. Among the Japanese brands, Canon, Nikon, Olympus, Minolta (or what used to be), etc all supply lenses to those equipment manufacturers or make such equipment outright themselves.
My aunt worked at Carl Zeiss during GDR times. It was one of the largest East German companies, and yes, the name still carried a lot of prestige compared to other companies.
This channel is underrated AF! Keep up the dope content
wild seeing oberkochen on youtube! my extended family lives there, it's a really wonderful little village (with a massive zeiss factory on the edge!)
I want to visit someday. I must have practiced saying that name 50 times!
Yea Germany is cool like that, you drive through some sleepy old village where you would expect time to stand still but then you will see their main business be some high tech company.
The only shame about the location is that it seems to attract dark clouds… worked for zeiss microscopy for 2 years or so, but the weather was one of the biggest reasons why I left 😅
@@Asianometry if you go there, make sure you visit the Zeiss Museum in Oberkochen. It’s only Open on weekdays but from what I saw it‘s pretty cool.
@@andyargentina7056 true!! so much rain haha
This is the most informative explanation of the two zeiss companies
excellent info about carl zeiss and his cutting edge breakthrough optical tech pioneering
Ich komme aus Jena, habe bei Zeiss gearbeitet, habe Zeiss Jena seit den 70ern verfolgt: Die Beschreibung im Video zeugt von hervorragender Recherche und ist frei von Ideologie, super! Danke!
I expected Jon’s work to be free from ideology but it’s reassuring to have that confirmed by someone who has personal experience.
Vielen Dank!
how was your experience at zeiss, talking to other people in jena it sounded like they had a bit of a problem with incestuous hiring and were very conservative towards new ideas.
Health insurance, pension, overtime pay and regulated work hours. Meanwhile the civil war had barely ended in the US. Really makes you appreciate these pioneers for what we have today.
Bosch has a similar ownership and governance structure to Zeiss.
That is fascinating! Thanks for posting it. I came here because I was curious about Zeiss lenses, but instead got an interesting video on the semiconductor business 🙂
Zeiss is also famous for surgical microscopy..I used it and was great
Carl Zeiss and Ernst Abbe really shaped the city of Jena and are held in high regards by its citizens like me, I went to the carl zeiss high school, a public school that puts a special focus on mint subjects and of course we used fancy zeiss microscopes sponsored by the company in the biology lessons. Because of Ernst Abbe in perticular the university of jena has a really good physics program with a big emphasis on optics and I am currently doing my bachelors in physics there too.
Good for you! You couldn't have gone to a better school for your chosen field.
Awesome! I am looking at schools in Germany to pursue graduate degree in physics/optics. Friedrich-Schiller University Jena and Leibniz University Hannover are the top two on my list.
Thanks. An idea : a video on Cymer light source !
This is why I like this channel. I've never heard of Cymer.
Zeiss had fantastic story.
Outside of the semiconductor work I like the story of the camera optics in the USSR and the Helios 44 lenses which are descended from the Zess Jena Biotar lens.
Also in the interwar period Nikon lured some engineers to Japan to help with optics and kickstart the Japan optics industry.
A huge part of the modern world is built directly and indirectly on the early work of Zeiss.
I live in the city of Jena. It is a clean and wealthy city and a wonderful place to live. The culture of the industry carrys on to the workers and the wider community.
Great video! (As always :-)
I don’t know if anyone mentioned it down-thread, or not, but the collaboration with Lawrence Livermore/Berkeley is why the US can control export of EUV systems to China. I don’t know the nature of the control (Perhaps patent licensing terms? Original development agreements?), but ASML/Zeiss are subject to US export controls, even though they’re not US companies, I believe because the US underwrote some of the fundamental technology development.
Yep its because US developed some of the fundermentals. Its explained in his EUV video as well.
Thank God for that... and good luck China taking one these apart and trying to copy it... Lol... Oh. uh we would like to order another one please... What happened to the last one?... Oh, uh... it fell on the floor and came apart in a thousand pieces... (shocked look on face)
The consortium that financed the 30 year long EUV research was US led (called Extreme Ultraviolet LLC) and they probably established a set of interests that were not to be violated once the fruits were to become ripe. Members of that consortium are: Intel, Motorola, AMD, Micron, Infineon and IBM, two U.S. national laboratories: Lawrence Livermore and Sandia.
Many companies are owned by Foundations.
Robert Bosch Co. For example. Inheritance taxes are very high in Germany. The Foundation protects sell off to pay taxes and keeps companies intact.
Thank you for this interesting video. Zeiss and ASML need each other.
Perhaps you can make a video about two other partners in EUV: ASML Cymer (Source) and Trumpf (CO2 Lasers).
Just today was looking into getting a salinity meter.. got to researching the refractometer.. perfect timing!
China desperately wants this kind of company..
A fascinating video! I'm watching this through a pair of Zeiss Intraocular lenses.
Another excellent video. May I suggest a few square meters of sound panelling glued to a shower curtain which you mount behind you when recording and another panel placed behind the mic ie on the side opposite yourself. The cheap stuff will do just fine.
What’s wrong with the sound? Serious question. Sounds like any other channel IMO.
@@codycast Oh no nothing is wrong with it. You just get a nicer sound if you record with a few panels like I suggested - less room reflections, less frequency doubling etc. Specifically you get less positive interference of higher frequencies which means the sound becomes warmer. Also reduces vibrational undertones which come from when the lower frequency sound waves hit the walls and other flat objects in the room. To be honest I don't think without a decade of sound work you will notice it, but I do. It's not a criticism only a suggestion.
@@mpireoutdoors5274 okay. I guess to me it sounds like every other channel. (I didn’t find your suggestion to be a criticism)
@@codycast Many other channels could also benefit from my suggestion... If you get better headphones you may realise what I mean.
@@mpireoutdoors5274 I’ll take your word for it. Though I’d guess 99% (?) of viewers jist have some wireless earbuds or PC speakers and call it a day.
Could you do a video on led chips and the manufacturing machine makers in the industry. It's all very shrouded in mystery how the actual chips are made and divided, seemingly anyway.
Very good video btw, exceptional exposition.
That's one BIG rabbit hole to dive down. NICHIA, OSRAM, CREE.... He could make a whole new channel just for that.
@@Molybed1 Yup, seems to have a few giant players and then lots of no name companies in the shadows doing assembly of the components.
Your videos are really of the best,
concerning complex technical devices and their physical backgrounds. Good training for my gray cells;) Thanks for all you produce, with passion, accuracy and free of pretentious posings. Rare qualities these days.
This is amazing. Thank you. I wish you could write article for WIRED so more people could know about a really interesting set of companies.
This is incredible
Very high quality video. I’m glad I have found your channel as it is has very high quality information and it’s also presented in an interesting way.
Do you mind if I ask you how did you get interested in this industry in the first place? Was it because you decided to invest in some of these companies?
He mentioned walking in on his father designing microchips. Maybe in the EDA video
Love your unbiased analysis.
Wow I never knew Zeiss was a co op. It’s really cool that the priority was on the long term well being of the company and the local community that it was a part of, and the results speak for themselves. American companies with their short-term gains over long-term pain mentality could stand to take notes. The only big American co op I can really think of is R.E.I.
I bought a Vivo phone because of the Zeiss lens. Love it 💕
It’s VERY cool that this company has been around for 200 years!
You missed the Zeiss PROVE, Merit, and AIMS products which are clearly IC related.
Excellent video, as usually on this channel.
Thank you for the time and effort that without doubt goes into these!
I find these one name, two companies shenanigans as explained at 5:33 quite fascinating since the history behind it is so interesting.
Pretty sure there are more examples, but one I can readily think of is Merck KGaA and Merck & Co.
Great video! We had jenoptics as a supplier and never made the connection with Carl Zeiss. Their EUV optics are a wonder!
Bidness meeting: We need to strategies to survive in this changing electronics world.
Zeiss: we're really good at lenses! We can work w/ the semicondutor company.
Phillips: TVs and consumer electronics aren't really a thing anymore. I know Healthcare!
Kodak: Lay off everyone. Sell the patents off cheap, give the execs fat bonuses, and bleed the company dry.
Lot's of people mentioning Bosch being structured the same way, but i didn't see comments (maybe didn't scroll enough) mentioning that they are dipping their toes in semi too.
They built one fab in Dresden and continue to expand it looks like.
If 20 years ago you had proposed building an EUV litho system with current-generation engineering and performance spec's, people would have thought you were completely out of your mind. If you showed them such a system they would have probably thought it must be space-alien technology.
These are incredible machines, for sure! But 20 years ago everybody thought that conventional lithography was on its last legs, and a switch to the EUV machines was just around the corner. Intel, other large manufacturers and government laboratories have created the EUV consortium just around that time, and the pieces of the EUV machines were already working in the labs. Intel hoped to have 13 nm EUV in production by 2007 and beta versions sooner than that. But it turned out that with various tricks one could print some features that were much smaller than the wavelength of light, using relatively ordinary lithography, so it just kept going and going. *That* would probably be more surprising to the people from 20 years ago!
@@cogoid Yeah, why not just squirt a pool of water under the lens, keeping it bubble-free and temp controlled to 0.01C as the wafer and mask are scanned at a relative speed of several meters per sec while their alignment is dynamically controlled to nm-level accuracy (taking into account the finite speed of light in the scan synchronization)? Sheer audacity.
i was an intern at jenoptik (light and safety division in hildesheim) but i never knew the entire history behind it, great video
I accidentally stumbled upon this video - it is really nicely made, even though the technical (read 'the cool one') part is not going too deep (though one can find some more videos on YT that offer that). I can only agree with what other commentators have mentioned already - the rather unique type of ownership of the company makes is less susceptible to market fluctuations and makes it easier to overcome times like 2008/2009 when revenue dropped sharply.
I watched a video that say if you were to move the lens module in an ASML tool across Germany made by Carl Zeiss, the Z height deviation is around 1mm. Crazy precision and accuracy is why I applied to AMSL.
Very interesting, as usual!
Woww...what an insight! Thanks mate!
Thank you for another great video
I also admire the Co-Op system. The only way to stop greedy execs and corporate raiders.
Extremely well done video
Zeiss even more so then ASML is a demanding but rewarding company to work with.
Thanks again.. excellent presentation crisp
Well made, I had no idea how important their product are for the final product for ASML lithography machines!
Let us know where is china in this regard ? Is the catching up working?
They are working on it
Thanks!
Great company producing outstanding quality. Thanks for the history.
I wish to one day be able to work for such a company where both profits but also the worker is taken care off.
Pretty instructive. Thank you very much.
11:16 Why do you need a citation? Just look at him!
Their largest product will probably be:
*Elephant B-Eyes 2000*
Joking aside, I love your techvideos!!
Would be nice to have a similar video on Nikon and Canon.
Panasonic and other Japanese companies as well, who became replacements for Zeiss in the mass consumer markets.
Collaboration with the China companies is new for Zeiss. Will the USA government allow this? Our just get jealous again?
I am working on it.
@@gregzeng US ban only works when a company used US technology. As for Zeiss is concern they surely not using US equipments in their production line. Equipment for manufacturing optic products can be found in Germany or Europe or Japan as US isn't a top producer of other kind of machinery outside of semiconductor equipment.
@@Asianometry It is really counter intuitive that ASML outsource its optics and beats its competitors who have captive optics knowhow. Afterall optics is the core competence in any lithography tools. This is a very interesting business case that debunk the usual MBA model..
Great channel. Maybe you can also do videos about Schott and Jenoptik, which were all founded by Carl Zeiss. This companies are also critical suppliers in the semiconductor industry.
From Wiki: Schott also produces telescope mirrors with diameters up to 10+ meters and---work in progress--39 (!) meters in diameter. Cast glass mirrors like that need months and month for cooling down, weight some gramms and are finally sanded as accurate as I don't know how accurate. Transportation to the telescope is another thing...
If you had shown some of their equipment to people 50-100 years ago, I bet many would call them alien artifacts.
"VEB stands for state owned enterprise" kinda hurts how much I've had to lough about this, not correct, but technically accurate translation!
speaking of jena id love to see one about Piezosystem Jena
Ernst Abbe was the most Important name for the Companies history.
this kind of technology is what china 's left behind..
True, though you might note that it's not primarily US technology either. This stuff is so difficult and expensive than it can only be done by massively multinational collaboration. Which is why no single country can dominate the modern semiconductor industry; they all need each other. If either China or the US has ambitions to be dominant or even just self-reliant in this space they are just gonna get their hearts broken after wasting a lot of money.
A fascinating history. Are you going to tell us how the ultra-ultraviolet light is produced? I'd love to see the machine!
from a drop of molten tin ...
Another German company involved in that: Trumpf Laser.
I'm not sure which is more crazy, the Zeiss projection system or the source.
VEB was not "state owned". It was "factory owned by the people". Huge difference!
Carl Zeiss says it all !!!
A sobering comparison can be made between Zeiss and Eastman Kodak,.
Jena is pronounced “yay-na” (long A).
Watching this video with my glasses that have Zeiss lenses.
Why did the US let the USSR have Thuringia? Here was Carl Zeiss based, here were the laboratories of Wernher von Braun and here was most of the art and gold stored under the big mines of Merkers and others.
They took the scientist in Thuringia, took the gold and art and left, because of this the Soviets were ahead of the US in terms of rockets, which were build in a labor camp (Mittelbau Dora) in Thuringia.
Russias moved faster torwards west
@@saschaesken5524 The USA were the ones who moved into Thuringia, in fact, the USA even were the first to move into Saxony and Czechia too.
@@Ghreinos ok thats new ro me
Jena roughly to be pronounced as "Yey- nah"
Interesting video. Just started to get into Semis so this is fascinating.
That makes sense since Germany has a strong socialist tradition especially before WWI. I respect that Zeiss treated his workers decently and explains why the Nazis wanted to take them over
Zeiss and Leica are two of the best optics firms, far superior to any Japanese efforts. But far more expensive so less well known except among real pros. A few phone companies however use their optics, among which is Huawei.
In eye glass industry aren’t as good as the use to. In fact they are behind some area.
@@square5726 Can tell you're not a pro. "Eye glass"?
@@Zerpentsa6598 Carl zeiss also manufacture eye glass . Although they aren't as leading innovator as they did. most of the new technology is develop by other company
Leica, the other fine German optic company, competes with Zeiss in some products such as binoculars but not the semi-conductor stepper market. Leica however dominates the high-end German photography industry with its M-series cameras and lenses. Today, almost all Zeiss-branded camera lenses are made by Japanese companies. I wonder why Leica never tried to break into the stepper market. Maybe it only has room for one player, at least in Europe?
Steppers are quite different from the optics themselves and there are several companies making them. You have to keep in mind that you mainly hear about EUV machines but there are hundreds of similarly precise machines in the industry made by other companies. Steppers are the positioning stages but many machines need precise positioning. The optics only deal with light and imaging.
@@excitedbox5705 Well I meant the optics in the stepper.
Well there is one other company called Berlin Glas that supplies ASML as well.
The 35mm Zeiss cameras of the 60s and 70s were excellent but so expensive, the Japanese undercut then. Sony was the one who bought up most of the camera market, but still uses Zeiss lenses under license.
Great documentary as always. I only wish you would listen at least once to the pronunciation of German Cities and companies (e.g. Wikipedia offers that), before speaking them. I does not have to sound native, but at least try to get in the ballpark. Probably applies to other languages too.
Carl Zeiss additionally owns Schott, which is also doing a lot of high quality glass.
From Wiki: Schott also produces telescope mirrors with diameters up to 10+ meters and---work in progress--39 (!) meters in diameter. Cast glass mirrors like that need months and month for cooling down, weight some gramms and are finally sanded as accurate as I don't know how accurate.

Noteworthy. A device called."The Zeiss Multiple Optical Steroptican Plentary Projector". Worth remembering as a Free Entry Password to the Hayden Planetarium a few decades ago 😀 😄
3:12 as a German I can confirm "Stiftung" is a distinctly German word and quite difficult to pronounce
no, actually I actually think it isn't. You can find English words which sounds like that. Like in "distinguish" the "sti" or in "shifting" the "ft". And for the rest, you have to be scottish to pronounce it right. :-)
