Here are pictures of two other experiments… the lettuce leaf again, but using a slide and cover slip, and a closeup of an LCD TV… ua-cam.com/users/postUgkxT9PSFmiJ3BtKD4F2CMJjoIJa1dcFjHAd
If you prepare things to look at on microscope slides, one technique is to add a dye that is fluorescent. It helps make parts of plant tissue or organisms in water etc. easier to see. The UV light makes this sort of dye fluoresce and do its thing. Hope this helps.
I vaguely remember doing something like that back in High School. It wasn't fluorescent, but some sort of liquid was added to the slide to help with visibility.
@@PhoticsTV Many dyes have been invented in last 20 years that bind to a single specific part of a cell or organism so that different parts of internal structures can be more easily viewed. There are dyes for cell nucleus, DNA strands, etc. All pretty amazing.
I really want it as I'm not rich enough to buy a bigger microscope without receiving financial problems. Disappointingly though, Amazon is not available in my country so ordering it comes with many extra costs. I wish Amazon would hurry here. Thanks for the review. It's very detailed and helped me understand how it works.
I'm glad that you liked the review. 🙂 Maybe one of these stores is closer to you? carson.com/customers/where-to-buy/ I saw Micro Center on that list. It reminded me of a similar problem. They often have the Raspberry Pi at a reasonable price, but they don't ship it. You have to go to the store. If I drove to the one in Brooklyn, the transportation costs could be more expensive than the Raspberry Pi… definitely more expensive than the Raspberry Pi Zero or the Raspberry Pi Pico. 😄 I saw that they have a Raspberry Pi 400 for $70. WOW! If the store was down the block, I probably would have that computer by now. But because the store is so far away, nope! 🙁
@@PhoticsTV Thanks for the list, but they're still very far away in another country. So guess I'll really just have to wait. Wow, that's something. Wish there was a stranger delivery service where you would just place an order and any stranger travelling from the store to near your place could just drop off the order after buying it for you. It would take some extra cost but what other choice would be there?
Have ordered one and waiting for it to arrive, what a great video! I think their official video says you can use the uv light to look at uv writing on things like bank notes
I'm glad that you like the video. 🙂 It does seem suited for looking closely at currency. Most things I tried, the magnification was either too strong or not strong enough. But with the dollar bill, that seemed just right. This is something I read from a PDF on the Secret Service website about US Currency… “Each denomination has a unique thread position and glows a different color when held to ultraviolet (UV) light.”
To use a microscope you should know slide making... Yo see good quality image, your slide should be perfect... A perfect slide gives you perfect image....so please next time try this with good slide making technic
The microscope I have included “1 Starter Slide with Cover Slip”. I saw on Amazon that this microscope is also available with some premade slides - but that costs more. A lot of the things I looked at in this video just don't work with slides… like the quarter, the hard drive, or the dollar bill. I suppose the lettuce leaf and the banana peel could have been sliced up and flattened, so I tried again with the lettuce… ua-cam.com/users/postUgkxT9PSFmiJ3BtKD4F2CMJjoIJa1dcFjHAd The picture does seem a bit more clear when using the slide.
Well, I've got my hands on one recently and I was somewhat underwhelmed by its performance. You know bad optics when you see it. The lens produces quite noticeable chromatic aberrations everywhere and the picture is not sharp overall. The picture quality at 100x is not bad, but I'd guess the maximum *_useful_* magnification of this microscope is somewhere between 100-125x and there's no reason to zoom any further, since you would just get the picture closer without any additional details revealed. On the other hand, I wouldn't say that it's just a toy - you can surely apply it to inspect microchips, blades of knives, banknotes, etc.
The microscope does have some usefulness, but I probably had too high of expectations for a $20 microscope. And yet, I recently reviewed a projector that was as low as $29, and I got a telescope that was $100. With all three gadgets, they seemed like a good value, but they would have been even nicer if the image was sharper.
It's always hard to use digital autofocus with incompatible optical elements (like telescopes, rifle scopes, etc), even when your eyes have no problem focusing. So maybe it could have been better if you just stopped focusing with your phone, locked its focal length and started using the dedicated focus ring of the microscope instead?
The problem with the standard iPhone camera app is that the long press lock is AE/AF… locking both the exposure and the focus. At least, I think that's why I didn't lock the focus in this video. This issue did reappear on the channel recently… ua-cam.com/video/MkCO5WV0iYs/v-deo.html …I had a great view of Jupiter in the telescope. I could see the moons. I thought it looked amazing. But when I tried to photograph it, the results were just a blurry mess. I tried using a separate app called AstroShader, which has a focus setting. I still couldn't get a good shot.
@@PhoticsTV the problem in both cases can be generalized as the need to manually align two optical axes perfectly and guess the focal distance right. And the problem becomes exponentially more complicated when you have the autofocus on. It took me almost 200 shots and manual focus to shot a few somewhat decent pictures of Saturn with its rings through the eyepiece using 50 mm lens of my Canon RP. So it's much better to use a proper adapter or a special astrocamera for such purposes.
carson has a smaller microscope with a smaller magnification (of course)...that is the microscope i was thinking to buy, but i came across another one that is extremely tiny, but i don't remember its name!!!
Did you mean The MicroMini™ (MM-380)? That's only 20x magnification. I originally got the MP-250 for a photography project, but the images weren't sharp enough. The one shown in the video seems best suited for looking at US currency. 😄
That's a great idea. I thought about revisiting this topic after seeing this video… ua-cam.com/video/KEwN6mqviY0/v-deo.html …it's about the before and after with a LifeStraw and Pond Water. I saw that recently and then I thought - that's what I should have done! 😄 That might make a good UA-cam short, but I don't have a LifeStraw… and those are not so cheap. I wouldn't want to waste it… but maybe just pond water is a good idea. It's been quite muddy in my backyard lately. 😊
I'm not entirely sure, but I think 250x means that the image is being enlarged 250 times. That sounds pretty big, but traditional microscopes can go much higher than that. Perhaps a recent community post will help you to visualize what's going on. It shows four pictures. Two are normal view and another two are from the Carson MP-250 microscope… ua-cam.com/users/postUgkxT9PSFmiJ3BtKD4F2CMJjoIJa1dcFjHAd
Good tool for only 20 bucks. I noticed there's some sort of rainbow in many of your images, like it couldn't quite focus the light - especially where the bright LED was used. I searched and found that cheaper lenses can be victim to this. It's called a chromatic aberration. I guess that is not surprising, but I do think it interfered with the image in some of them.
It's tricky to keep the iPhone centered in the clip. It slides around. So, I'd grab the microscope and try to straighten it, but then I'd touch the focusing dial, and then the object would move. Then I'd want to zoom and the process would start over. Heh, there are a lot of pieces that can move. 😄 But now I have to decide - is it worth getting a proper microscope for the photography project? Interestingly, I saw a commercial on UA-cam that was very similar to what I was trying to create… ua-cam.com/video/aDuearaV070/v-deo.html
It is possible to look through the Carson MP-250 Microscope without a smartphone. I just tried it. I could see the printed dots on the box. But to make this video, I had to use my iPhone to record what was being magnified. The Carson MP-250 doesn't make pictures or videos. That's the job of the smartphone. The AA battery used by the Carson MP-250 is to shine a light on the subject… there's a button for LED and another for UV.
Thanks for for the review. The aberratics chromations are pretty pronounced (the price is low it shows ) so I don't know what to take, would like something to inspect some blood cells
I don't understand your question. 🤷🏻♂ There's an LED light, which faces downward. Pressing the LED button toggles the light on and off. That light is for illuminating the subject to be magnified. That's shown in the video. Without the light, the image could be very dark.
what downward facing led?my mycroschop downward facing led no glowing but front facing led and uv light glow all pocket mycroschop downward facing led glow/not glow?? sir please answer my question
@@girijaghosh52 The other light is a UV light. Ultra-Violet light is invisible to the human eye, but a blue light should turn on when the UV button is held down. If you're not seeing your LED light work, then perhaps your microscope is broken - or maybe it just needs a new battery.
It's a neat gift idea. If I was doing the Twelve Days of Christmas playlist when this video was created, the microscope would have been on the list. It's still only $20 at Amazon - nice stocking stuffer!
The magnification I was using was between 100 and 250. 😄 It zooms. The documentation mentions a "Zoom Dial"… media.carson.com/repository/doc/MP-250-Guide_EN.pdf The exact zoom for each item, that shown in the video, was not specified. However, I think that I generally used the maximum zoom. But as mentioned in the video, the Microscope has an awkward range. I felt that the magnification was either too close or not close enough.
My Carson MP-250 is in storage, so I couldn't test this. But in the description for this video there's a link to the Amazon listing. The question… "Do I have to use my phone?" …was asked. A response from the manufacturer said, "You don't have to use your phone. The adapter clip is a separate piece that easily attaches to the eyepiece if you would like to use your phone, but it is not necessary."
I'm not sure… but I think the UV light might have something to do with fluorescence. 🤷🏻♂ This video is fairly popular. So, I just started a list of “New Microscope Experiments” that I could put in a new Photics.TV video… and “Something UV” was added to the list. 😄 If I get around to making that video, figuring out a good use for that UV light… or at least makes for a pretty picture …seems like a fun experiment. 🙂
@PhoticsTV Yeah, but I believe the reason it keeps going out of focus is because the iPhone camera is trying to refocus. The microscopes focus is fixed unless you change it manually. Correct me if I'm wrong, I was thinking of buying one. Most other videos the focus seems more stable.
@@SC-qi1pz It's been a while, so I don't remember for sure, but I thought I would have locked the auto focus / auto exposure on the iPhone. There's a focus ring on the microscope. That's a big part of using the device. (It's mentioned in the User Manual/Guide.) media.carson.com/repository/doc/MP-250-Guide_EN.pdf I wasn't flattening the objects, which is why there's such a big range of focusing. I wasn't using the slide like a more experienced scientist either. Keeping the iPhone focused is important, but I remember using that Focus Ring a lot. That's part of the art in using this device.
I watched the video again. It looks like Auto Focus / Auto Exposure lock was not on. You can see the iPhone working to regain focus and the exposure. That's shown by the yellow square. It seems to recover pretty quick though. Now that I think about it, I'm not sure if I'd want to disable the auto exposure. While locking the focus might work, since the camera doesn't move in relation to the microscope, the level of brightness could vary depending upon the subject. But basically, I was using the focusing dial on the Microscope a lot. My subjects weren't flat enough, so there was a lot of variance in focusing.
@@joemama106 Thanks! 🙂 That's my voice. At least, that's what I sounded like almost two years ago. I put a lot of work into these videos. There is editing involved.
