- ITS AWESOME!!!! That is all!
If you want one, just search ebay for 'dichroic cube'. You can pick them up for a few dollars.
I fear to write anything in the description these days as it just seems to get thing demtzed! :-(

Im not getting anything by selling these... theyre just AWESOME!!!!
just search ebay for ''dichroic cube' :-)
Why am I not seeing an AD on this? Refreshed it 5 times already.
"Dispersion Prism X-CUBE" is a better search term.
eBay is full of scams, avoid and buy from amazon or legit online sellers with real websites. eBay fees are also insane, avoid fleaBay. Everyone gets scammed once or hustled by a liar on ebay, nobody can deny it
derty QWERTY eBay is amazing, I don't know what you're talking about. Don't buy dumb crap from sellers with zero rep
I've bought hundreds of items on eBay and so far I've never gotten scammed even once. I haven't ordered a single item from there where I felt the shipping was unreasonable
For those who aren't colourblind I'd like to share my experience.

Why isn't this video called
"Super Freaky Diochric Sexy Cubes?"
*Solar freaking thorium dichroic crosses that makes water out of the driest desert's air*
AlanKey86 because using the term sexy for something that isnt sexually attractive is pretencious and embaressing
gone sexual

I have a feeling that being stoned in thunderfoots house could be a lot of fun.
Best trip ever
I sort of think he was on this one XD

it's just as much fun getting stoned and watching the videos

I was watching this in awe the way your were showing how the light works going through those cubes, so I called my wife over to show her how pretty the light and all that, thinking she'd be impressed. Well...
At least I think they're cool and want one.
That was advice, not an insult. My apologies 👌
Would have been cool if you'd talked about thin-films and why these things work. Some absolutely fascinating science behind it.

It should be, we could use a little Jeri Ryan action in this channel!
Go back to January where you belong.
30 Seconds into this video and I'm already looking where to get one for myself! Also as a Lighting Designer for theatre, Light Science is something Ive studied for years and Love and Never heard of these things. Thank you SO MUCH for sharing this!
The old style dentist lamps (200W halogen) use a dichroic reflector to reflect mostly visible wavelengths (combo white) while allowing significant amounts of infrared to pass through (so that the patient isn't slow roasted).
Really? Interesting
@@DANGJOS yes
I completely forgot about dichroism. Optics and crystallography really shouldn't blow my mind as much as they do, it's largely geometry at these scales, but they're just endlessly surprising.
TomatoBreadOrgasm the lights are dazzling and attractive, its hard not to be constantly amazed by them
they're basically like hobbits!
Yes, crystallography is fascinating! Did you know aquamarine can help remove negative energy and clear your chakra?

Just because one understands and knows it, doesn't make it less beautiful :)
I thought I just getting a Thunderf00t's Pink Floyd Playlist intro from that thumbnail.
Your enthusiasm is so infectious! Thank you for being a timely reminder for me! :)
I like how he has Microsoft Edge, Firefox, Internet Explorer (somehow) and Chrome all pinned to his taskbar.

Standard setup on a new computer. Some people just dont care lol
This is usually done if you do web programming and use all browsers to test it since each browser works differently (especally edge, the fucker)

Miss Firefox.
Boooo... Doze 🤣
We use a lot of these optics in laser show projectors. Specifically dichroic glass for combining the red, green and blue wavelengths into a single beam, and often times polarizing beam splitters for combining two diodes of the same or similar wavelength before sending it to the dichro array to join the output beam. Even having worked directly with this stuff for years it still amazes me.
You should seriously upload more frequently mate. Your vids are awesome, keep up the good work.
YT is not his main job and if he keeps up this pace his videos keep being high quality
Thunderf00t, love your channel. I learn so much about science by watching. Thanks.
Thunder foot thank u so much for showing me something that's so awsome but that iv been overlooking for years I now know what I want for Christmas thanks for making the everyday amazing
I am working for a manufacturer of projectors. We use dicroic mirrors to combine light from 3 LEDs, send this to a DMD chip and then through a lens. It is so fun to watch these things in action.
Just now saw this video from you and it has inspired my creative side! My mother and brother both have birthdays coming in a few months so I'm going to get a few of these nifty little cubes and put them on a rotating pedestal with an LED light behind it so that it'll slowly rotate through the colors. I think it'll make a nice little (mostly) homemade light that is a lot more interesting than just a basic color changing desk decoration.
I just bought a couple of these for a Christmas present, I'm so excited!! Thank you for making this video
Always look forward to the nice bit of reason and knowledge thanks Mr thunderfoot.
My dad worked for NASA as well as the DOD and was part of the optical engineering teams that created the "cold filters" used in many different applications. He gave me many different types of dichroic lenses in all sorts of geometry to play and experiment with. He would give me lenses and different types of lights and I had to write up my findings. I felt like a real scientist and nothing could have made me happier.
Well thunderfoot you have given me the best holiday gift idea! Kids are gonna have a blast AND be wondering what's going on!! Cool and learninfull!!
man you have been touching on subjects that relate to my own research for my 3D printer, and the material science behind it, as well as the recycling/refining unit and some of the energy research to power it all, lol.
I love this video because it's just honest. Thunderf00t found a really cool thing and shared it with us.
thunderf00t, thanks so much for not spoon feeding me on exactly how they work, I am off now to find out for myself :)) these things are incredible!
These are great for combining lasers, I plan on using one to make an RGB laser. Idk if this was mentioned I didn't watch the vid yet, but it's actually two different dichroic mirrors glued together, one reflects blue, one reflects red, but green passes both, explaining the green effect. And when you rotate it most of the light goes through the glass hence white light. They are also used to combine infrared and red lasers in cd/dvd combo players. Again I didn't watch the vid yet I might be repeating stuff.
Thank You Thunderfoot...often the 'simple' things that mean so much . Cheers
Very cool, and what a great use to put them to in the projectors.
Your passion for science is infectious
When I was a kid I took things open, and i've found one of these cubes (very small) in a cd player. Thanks for letting me know what this is Thunderf00t!
love your enthusiasm.
Adding this to my wish list! Thank you VERY MUCH!
This is awesome on so many levels. I might get myself a few of these.
Thanks Phil. I was struggling to think of something to buy my 85 year old retired physicist dad for Xmas. I think he must be bored with just getting a bottle of wine every year. He will love one of these. The funny thing is, my mum is not exactly scientifically literate, so my dad and I will probably spend much of Xmas day afternoon trying to explain to her how it works. Happy Xmas.
Dang I love your channel @thunderf00t!
I'm getting one of these soon for a projector I'm building, this was super helpful
I need this for Christmas! great vid!!
I used to have one of those cubes when I was a kid. Good fun with light, educational.
Thoroughly love your videos. Purchased
love your passion while talking bout it..
Hey Thunderf00t, you've given me a great idea for a potentially amazing disco "ball". I can't wait to start designing it. But I have to work in the morning.

I love these things!
I gave them as stocking stuffers last X-Mass.
Double like for showing us this, i had to get some for myself, these things are awesome
I love your videos. Rich content!
You are having too much fun with these thunderfoot
I've a few of these, great things to play with. My big one sits on a "tensegrity table" beside my solar radiometer. Fun way to occupy the mind when at a loose end.
Thank you for showing this I ordered one last night.
Nice video, simple yet cool. Like it.
Thanks dawg, these are pretty cool. They'll be good presents for my lil broskies
Buying them now, thank you for the tip. Ebay lists some as hot items, China must thank you for the shout out ;)
Thank you for the Christmas present idea
Mind blown!, thank you Mr. fOOt.
as soon as you said what they were called i hoped over to ebay and bought one :D
"Now go home and get your fuckin' dichroic cube!"
-- Frank Vincent, Goodfellas, 1990
Might pick some up - Sounds like a low-budget filmmaker's dream come true.
This is fascinating and I love it! Disco lab!
I just ordered 4 of these. dang i bet the seller of these cubes are happy about this video! even if only 1% of people bought some after watching thats a 1000 extra sales that they probably wouldnt have had otherwise.
Thanks for the christmas suggestions
More videos like this! I love scientific curiosities.
Went straight to eBay, top bloke.
I have to get a couple of these!
I laughed like a child, this is awesome
That is neat as I like interesting things which illustrate scientific principals
That was really cool! Thanks.
Does the light intensity stay the same on each splitted beam, or is there a difference? Would these things work with other wavelengths of light than just visible, as shown here? Those cubes sure are cool to play with but I just don't see any application.
Serious post here.
IMHO, it's time for merchandise. Thunderf00t lab coats, prisms, dichroic cubes, spectroscopes... Lots of stuff for kids to do. I trust your judgement over mine or any general supplier whom I don't know. Ok, I don't *know* you but I reckon that you are as you appear, and that is mostly a fantastic educator.
My 10 year-old grandson has just been made "science ambassador" for his SEN class. If other kids are having trouble, he's to help! We are SO proud, especially given his own... quirks. That'll do. He would love stuff from a web celeb 😁. My biochemist son's in charge of buying science pressies for his niece and nephews, and anyone else who would like one, but he's not allowed to nick chemicals from the lab! Not after... Oops? LOL just kidding. Or am I? 😎
Back to being serious; I've seen a v interesting chemistry channel on YT which shows, amongst other things, how to grow your own crystals - different videos covering different chemicals/techniques. He says that the chemicals can be found on Amazon or other websites - a) that's not very helpful and b) if it were up to me to get the stuff, I wouldn't trust myself to buy the right - safe! - things. Not to mention he has big pots of the stuff. I think an ounce or so would be a more appropriate size for kids' experiments (under supervision, of course) at home. You could write up instructions maybe, or do a video for each? I'm all for immersing my grandchildren in science from a v young age but it's got to be appropriate - no small, especially strong magnets for the 2 year-old for example. You could give reassurance regarding the right age group.
No, I don't want you to stop doing your usual, top-notch videos, but as you yourself said, you wanted to come back to doing science and not cliquey sceptical stuff, and whereas I doubt you'll stop being sceptical (good!), doing it on your own terms and in your own time is by far the better choice IMHO. I'm not sorry (even though I shared your opinions virtually all the way), I get more fun watching you do science, engineering, and taking idiotic "inventions" apart.
But it couldn't take *too* long to get some glowing blue balls to sell, could it? 😉 It could help fund your videos, too. If you want to look into selling t-shirts, hoodies, maybe even lab coats 😇 there is a company which allows you to give a cut-off date for orders, and if you don't reach the desired number for the most cost-effective run, you can stop it before they start printing (obviously, no money from punters until the items are ready). I got an amazing t-shirt through a charity recently which had been mouth-painted by Henry Fraser (I follow him on Twitter. It has a beautiful tiger head on its front and everyone who sees it is jealous! And yes, it's all based on the painting he did only using his mouth to hold the brush!). It is good quality and a reasonable price (about £15 IIRC - or not far off), sold in aid of charity. Maybe they have a more commercial... Was going to say "arm", but I'll leave it there...
Please don't dismiss this out of hand! I'd be prepared to proofread your web pages for it. I've volunteered to proof for charity fundraising, an online shop, mid-Atlantic sci-fi (we wanted it understood by all English speakers!) a couple of dissertations and currently a biochemical thesis and a medical diss next summer. I have 2 BAs from the OU covering a wide range of subjects, inc some science, but mostly linguistics and the technical side of music (I had to proof a handwritten score by Handel for half my own diss! Bloody awful handwriting!). Also have recently joined Distributed Proofreaders to help get out of copyright works online. So I have a few decades of practice at doing it and offer my services free of charge should you choose to go ahead with it. I'm stuck at home more often than not, so I usually have a lot of time. As an aside, I could go over your videos before you upload if you want?
Ann other pear off I's rare lea Hertz, moor off ten 'it yelps ;-)
Sorry for dumping this on you, especially just before Xmas, but I honestly think it would be popular with your loyal followers and could help keep you online and us on our scientific toes! I'm sure that you have other followers who have a ton of experience in setting up businesses online and maybe an accountant to help out - *all volunteers*!
Anyone else agree? If you really don't want to go there, and this post becomes a nuisance, say so. I'll pop back in a couple of days and take it down if you want, or you could do it yourself. No offence taken on my part if you do. If you want me to go over anything, let me know on this video your preferred way of how to contact you.
This is another one that Tim from the Grand Illusions channel would love.
My cube has arrived. Cant stop looking at it. People at work think im odd. My little girl is going to love it! (She better had anyway)
A mobile hanging in a window made of these would be pretty awesome. Attach little vanes to the bottom of them to catch little air currents to make them spin and twirl around.
The genius part has to be in figuring out how to manufacture them.
A single beam splitter is relatively straightforward, but building two perpendicular to each other... That's the kind of thing that would make engineers cry in despair.
Do you think if you got 3 100w RGB LEDS and placed them where the LCDs would go (each colour into its respective side) - would they combine to create bright white?
What happens if you try to split one of the colors that have already been split like the red or blue with another cube? Will it make three beams the same color or what?
Davis King the original colour should bend if it wasn’t green but the other colours would be very faint as there is very little other colour light left in the splitter output.
Davis King probably will have one main beam in the colour you’re throwing at it and two very dim beams in the other colours, because I guess $2 pieces of glass don’t split chromatically perfect. But i don’t know, just guessing
...it would probably stay the same as these cubes are basically four prisms glued together. Similar experimet was conducted by Newton who shined beam of white light onto one prism, isolated the beam of single color, and then redirected that beam into another prism. Color remained the same, therefore proving white light is actualy made of all the colors . Here's the video of that experiment: ua-cam.com/video/--b1F6jUx44/v-deo.html ...:)
I assume that the light will stay the same color through the second cube because it has already been filtered into the different wave length, but the only way to know for sure is to experiment and see what happens. I don't have a couple here to try it myself and I don't plan on buying any so it would be really cool in Thunderf00t does it and reports the findings, just to satisfy my curiosity.
They are pretty fun. We have been working a little bit on using a similar optical construction to build a thermal imaging camera in the lab. By splitting the the beams and doing correlation you can actually derive the long wave length parts of a picture with one of these and a standard RGB sensor (if you are interested you can look up Horton, Mitchel Dewayne, "A Novel Technique for CTIS Image-Reconstruction. "). However it is currently a very long computation to do, so it isn't really practical for a real-time video camera yet. Since you have done a lot of great thermal imaging videos I would just let you know the true awesomeness of what is possible with optics these days. You seem like you would appreciate it.
I love your channel
I was waiting for you to put 2 in line.
such a simple concept but very usefull
just looked them up on ebay - they have gone up in price! - thank you for sharing
Nice, pulled some from a salvaged RPTV one time and must of played with one of these for ages. Had always wondered more about it. Also found a lot of other amazing pieces of ,.. whos knows what, but some were transparent until combined with others and rotated to make blues, reds and greens. Also some ridiculous lenses, multi lenses in one and other lenses that I have no idea what to call, recommend diving into a more modern rear projection TV and pulling some amazing stuff.
TIL Thunderf00t is colorblind
You have several Motherboxes. Steppenwolf will turn up with his army of Parademons and try to claim them.
Absolutely great video that I might use if I start tutoring film again!
That said I have to nitpick. You called magenta “purple” and you called yellow “green” and cyan “green”
Sorry, had to nerd at you. Love your science videos, please do more!!!
+Thunderf00t Can these be used in astrophotography with three monochrome cameras? I couldn't find anything about it, people instead use RGB filter wheels.
Does anything interesting happen when you flip it on its side and shine the light through the top or bottom?
what if you put one on the blue/orange end of the light? will it only deflect the same color or will there be other colors
So what do I craft this “dichroic cubed” from? Can I use it for some sort of buff, or is it purely to guide me through the maze of gyartyloh? Other than these questions this guide was quite informational!
How is the colour coming out of it if its pure glass? Magic?
For people not afraid to be seen dumpster diving: many projection TV contain a few dichroic optic.
The shape to look for is a large flat screen and the back cover slanted about 60 degrees (0 degrees being horizontal, 90 degrees the vertical line of the front), There is two models:
Model with 3 micro mirror array:
The white light from the arc lamp is separated into 3 colors using many dichroic optic
The image is formed on each mirror array
A cube prism combine the 3 images for projection
Model with 1 micro mirror array:
The white light from the arc lamp goes thru a color rotating wheel
The mirror array produce each image synchronized with the color wheel
The image is projected as is
Brief, there is no cool dichroic optic with the model that use a rotating color wheel.
Beside the optic, I keep the arc lamp, the inverter that drive the lamp and the 400 volt power supply. The lamp is 100 watts, 60 hz operating at about 100 volt when warm. The light intensity is high enough to burn the skin at a distance of 3 feet. You can replace the incandescent bulb in older projector... Create a light beam scanning the sky like in some circus/amusement park or large sports events, ....
The inverted just need the DC power input from 320 volt to 400 volt... no need to be regulated ; just a diode bridge and capaitor would work and it need the turn on command from 3 volt to 12 volt applied on two of the pin on the small connector ; it is 3 opto-isolator... no danger to experiment until you find the correct 2 pin.
A perfect gift for my nephew. I'll just tell him that this is the "cosmic cube" from the Avengers movies LOL....
TF00t! PLEASE RESPOND TO THIS!
What happens if you rotate them around the X axis rather than the Y or Z axes?
It's driving me nuts that I can't work it out!
This is awesome!
Hi Thunderf00t, do you know if the rgb outputs of a dichroic cube are coherent light?
Is it possible to drill a small hole and put a string through it to make a necklace, or would that destroy the effect created?
You are having way too much fun here. LOL
So basically prisms interfering with each other. So simple but fun. Thanks
Do dichroic cubes work based on wavelengths alone? Is there something else which behaves in the exact same way but only based on light polarization
