      You missed the diy route.
      You could purchase C/CS-mount or M12 mount lens. Its $10-$20 for those 100x-180x.
      Then attached said lens to an old phone/dashcam/action cam bare sensor. You could already have it so you don't need to purchase, I've used an iphone 7 and it works.
      Bare sensor is the keyword here, you need to pry off the LENS on those to have the bare sensor (squarish). You could hot glue or 3d print an adapter but it works.

      I'd love to see some more intermediately priced models. Like below 300, 500, 1000, and so on.
      It is no wonder, that microscopes for 10 bucks don't rock your world. And if it was sold for 10, it was maybe built for 3.
      But it doesn't need to be the 50.000 bucks Keyence monstrosity to get good digital photos.

      I bought a Celestron 44302-A branded version of the third (Shiiri) and fourth (Oxbird) years ago. It seemed to be a no-name made USB device that was widely available under different names... you are right, the result is "disappointing", and is not really a microscope. It has it's uses for me, however it was barely worth buying.

    These cheap USB microscopes are actually pretty useful for servicing electronics and watches, also taking very little space when not in use. And these do differ in magnification. Less magnification is better as it's easier to position and focus. Their online descriptions are however all over the place, so you'll never know what exactly are you buying.

      I started using these few years ago on microelectronic repairs, and they work just fine for some uses. When you need to improve the precision on your work, they can become insufficient, but that doesn't mean they are bad at all.
      It depends much on what type of job you need to do, so maybe spend hundreds or even thousands of dollars on fancy high-end equipment just doesn't worth at all, because you can do the same job with a simple and cheap microscope. Don't you think?

      Unfortunately they are not very good when you need to repair laptop motherboards or something larger because they either have no mount at all or are bolted to small table which pretty limit the usable area. Also due to diffraction and zoom artifacts it is difficult to see small IC and connector pins at most angles. Another drawback is low frame rate and data transfer speed where picture of observable area is a bit jerky and appear after some delay which become very annoying when you are soldering IC in LQFP-64 package for example. But yes, they are usable in simple cases.

I'm a hobbyist repair person who does these things because I enjoy the job, helping other people is pretty good as well, and to spend upwards of GB£300 on a scope (for me) would be a ridiculous waste of money that I would never recoup.

    Another option, if you have a C or CS mount camera (such as the Raspberry Pi High Quality Camera, with it's 12.3MP Sony IMX477R sensor) is just to buy the optical components you need for your use case. A simple C-mount adapter, extension tube and objective lens system doesn't have to be that expensive to achieve better results than the tomlov.
    We used to buiId application specific optical systems like this all the time when I worked in Machine Vision (metrology for robotics applications), and back then it was Firewire or GigE visions cameras like the Allied Vision Guppy sensors, but these days a Raspberry Pi High Quality Camera + Zero 2W would make an excellent headless WiFi camera host, which you could plug a monitor into, if a big screen is needed.
    This industrial optical component 'lego' approach is the perfect half way house between buying commodity consumer kit and buying a full on scientific/industrial microscope.

    Great video! It's bugged me for at least 20 years that manufacturers (even the ones that aren't random names from Amazon) like to obfuscate and miss-sell their products based on marketing. When digital cameras first came out we had the huge MP claims, only for them to be 'interpolated'. The only reason to do that is to con people. These days it's fields of CCTV cameras and dashcams claiming to be 1080p or 4K, when in reality they're all 480i or 720p.

      There are too many dumb people, that falls for it. That's the problem.
      I have had it so many times people who claim for example that their cheap phone can film in 4 K or even 8 K - and it can be a hard time to explain that even if the frame size in the files is 3840 x 2160 or 7680 x 4320 pixels, doesn't mean the camera is able to film in that resolution. Same with many other products. Many of us have probably seen those ridiculous 3 million volt tasers or stun guns on Amazon or Ebay. But a friend of mine (which I didn't even had a discussion with) got surpriced when my BMPCC 4k gave much more detail and sharpness and dynamic range than the 8 k HDR, his phone claimed to have.
      In many other cases, the sellers also don't obviously lie in the spec, but rather give the specifications under conditions that's unacceptable, unspecified or impossible to reach during normal use.
      For example speakers/headphones or even microphones are sold everywhere, that's claimed to have a frequency responce from 20 Hz to 20 kHz, but have no given tolerance limits for how much variations is allowed within that range - which makes that info useless (it's output or sensitivity could as well be down by 20 dB at the ends of that range - making it's practical useful range much less).
      Another example is power components - for example transistors. The current handling capability put on sellers sites, is often given at 25°C case temperature and maximum heat dissipation at the same time (which is impossible to reach, unless active cooling is used or ambient temperatures is very low - active cooling is usually not worth the added cost, maintentance and noise. It will often also reduce overall efficiency of most systems, as it takes energy to run).
      At least those comes with data sheets that show more relevant data, that can be checked before buying.

    An important parameter is resolution, being the distance between two points that look like two points rather than one. Magnification without resolution just makes the fuzzy blob appear bigger. Also, always try to use an in-image size-bar with clear markings as to what size and units it is, like "5 um" (ideally the mu symbol) so it doesn't matter what size the final printed image ends up being.

      @quetzalcoatl-pl Рік тому +3

      That's also my thinking. That's why with the "toy-scope"s I tried out I always tried to measure what was actual real-life distance between two pixels on the final digital image (of course, provided the image is in-focus, clear, etc). If I photographed a 0.5mm test ruler and ended up with crisp image of it spanning over 50pixels, then no matter how I view it, it's 10micrometers per pixel and I won't be able to even tell things apart from each other of anything smaller than 15-20micros, and if I want to see any actual features then I can forget about looking at things less than, say, 100-200micros (that will map into 10-20pixels in this example, who's gonna tell it was a sonic sketch on a 10x10.. a pointy ear would be probably 1 pixel tall). Having these x/y pixel distances (because sensor may have uneven pixels, and aspect ration doesn't have to be 1:1), then I could do some math - video sensor has this height and this width, this many pixels vertical and this many horizontal, I could calculate single pixel size on the sensor (sometimes it's even given in specs), and then real-life x-y pixel distance to on-sensor pixel size should give the true magnification ratio of the device. But then.... what I care in the first place wasn't the magification, it was how small features I could tell apart, and that first simple distance-to-pixels check was totally enough :) "Mag:200x" looks great on the video, but to be honest, I would LOVE to see a scaling ruler with "|| 1.0um" marker instead. It's so much more informative than 50x or 200x.

    I think you could check one possibility of a hidden magnification step in those cheap toy-microscopes. Long time ago, I have bought a, hm, say, microscope, called "Supereyes A005+" which boasts up to 500x and 5MP. It looks like pen, a bit longet, and a bit thicker pen. It has a similar build - tube with roller and the inner optics slide up and down as you roll. It's much thinner than your $9 microscope though. It wasn't exactly cheap, but costed way less than a real one. Opinions were mixed - many comments claimed it to be a scam and not real 500x, but some actually provided important insight: the thing has TWO focus points when you roll. The first one, say, position 0-95% of rolling, is the low-mag part. Optics are mostly inside the tube. That's where you get lets say, up to 100/200x. But if you roll it all up to vicinity of 100% (optics slided down as much as possible, almost sliding out of the device) then you might be able to catch a very tiny spot of good focus again. The first lens will be like 1 or 2 millimeters from the inspected object, almost touching it. I like to joke that it's pressing its video sensor against the object :D Quite awful working distance. I scratched a few objects that way with microscope's chassis. But it actually gave higher mag than the easier-to-use 0-95% slider positions. I'm not sure if it was really as advertised 500x though. I tried to measure it, and I'm pretty sure I remember it could produce resolution of the order of upto about 10 micrometers per pixel. No idea how that maps to 'times' metric.. Now, what I'm getting at is -- I've read that SOME of those cheap microscopes actually have the same feature. Is it worth checking with your lab? Or is Supereyes A00x/B00x worth trying out? Well, I'm interested, but viewers probably won't. It seems to be dying brand. If you would like to hunt for them, watch out the model numbers. Their specs vary greatly. The one I have is/was A005 with a plus. It's was advertised as different than A005 plain.

      This is my experience with two of these scopes so far, too. There's a certain threshold you pass on the winding mechanism, where it doesn't seem to be crossing from optical zoom into digital zoom. Rather, things go out of focus and then back in again with better detail, as if there's some real change in the focal length or something. Edit: For example, I used one of these cheap scopes in the first section of its sensor range to photograph a dead fruit fly such that you could clearly make out its basic anatomy... but then, in the second section of its sensor range, I managed to take a photograph of another dead fruit fly where you could make out its individual compound eyes.

    Nice comparison, but I suggest that you compare the magnification when looking at the images at the same pixel magnification. Even if the "8 MP" and "16 MP" images show the same field of view than the 640x480 images, you could scale them to a much larger size without loss in quality. That being said, of course "x times magnification" is of course only an advertisement trick, because you could just take your 640x480 picture and project it to a wall and you get gigantic "magnifications".
    So an additional, valuable criterion for your comparison would be: how many µm per image pixel, or what is the diameter of sonic in pixels.

The magnification number is nearly meaningless when you project the image on a sensor and show it on a screen. Life hack: 10x your magnification by copying the image into paint and using resize.

But one has to admit that they are pretty cool devices given the price. Real optical microscopes have big advantages but having a flexible magnification range between 10 and 40x is also interesting to capture quick full size silicon die shots. This closes the gap between macro shot with a regular camera and high mag microscopy pictures. So in the end it depends on what you want to to…

    Thank you for the comparison and views into the internals of these microscopes.
    I recently bought one of those very cheap ones and I was actually pretty impressed with the image quality.
    Sure, I'm not using it to inspect transistors on silicon but the max 100x magnification is ideal for reading numbers of these tiny SMD components and for checking soldering joints.
    So whether one is going disappointed depends on the expectations one has before buying, and of course your video helps to manage them.
    If one buys a hobby telescope, thinking to get images like those produced by Hubble, it's going to be a major disappointment, but seeing the bigger moons of Jupiter or Saturn though one of these, pinpricks that they may be, can be equally rewarding.
    Regardless, the performance that the vendors are advertising are just as misleading as the "4800 DPI scan resolution" of the 300 DPI flatbed scanners of decades ago.
    Mega resolution through software interpolation should be forbidden in advertising.

    I have to say, these cheap microscopes are still definitely worth their while as novelties. I bought one, and it has definitely been fun photographing the head of a pin, the edge of a razor blade, the individual pixels of my smartphone's screen, the individual ink dots of color newspaper/magazine print, handwriting from a ballpoint pen, paper fibers, cardboard fibers, the grooves on a record, the fabric weaves on a woven phone charging cable, plant trichomes, my beard stubble... I could go on and on. They do fill a nice niche between macrophotography and proper microscopes, though it is a definite bummer that they tend to only have VGA sensors.

    Have to admit I did buy one of those cheap ones, but I didn't expect it to be all that great, simply because generally you get what you pay for!
    However, 20yrs ago when I first began purchasing stuff on eBay I bought a Pentax camera/microscope-adapter but never did use it on any of my Pentax film SLR cameras. Having bought a Pentax K-S2 DSLR a couple of yrs ago, I thought why not make use of the adapter, so I looked at what I could afford in the way of optical microscopes. Ended up using an eBay voucher to save almost $55AUD on a $249AUD Celestron Labs CM1000C Compound Microscope, which means I can watch a very good image on my PC's Samsung 32" QHD monitor, while operating my DSLR using the app on my mobile!

    Magnification is not an important spec for a digital scope, because any image can be infinitely magnified. The things that matter are resolution, dynamic range and depth of field, in that order.
    A 0x magnification scope (where 1 micron on the object is 1 micron on the sensor) is about as good as you can get. Displaying an image from a 1/4" sensor on a 25" wide screen gives 100x magnification. Displaying it on a 50" screen gives 200x.

    Good info, thanks.
    The resolution reported in Windows is purely down to the configuration data that is configured to be reported over USB and this is entirely configurable therefore it is an indication of the claimed configuration, not the actual configuration. There is usually overscan on these sensors therefore the product sheet reporting a slightly higher resolution, for example 648 x 488 is just because there are 4 pixels overscan all around (you can even see these slightly differently configured sensor clusters when you zoomed in. This doesn't necessarily mean that 640 x 480 is the final resolution because in order to enhance the quality of the image it is possible for multiple images are taken and/or interpolation to be performed which boosts the raw resolution somewhat. For example, with interpolation it's quite valid, if a little disingenuous, to claim that a 640 x 480 sensor has an output of 1,280 x 960 pixels. Add in digital enlargement of the image and if Windows is informed by the device that it has a 2,560 x 1,920 resolution and the device buffers and enlarges a 1,280 x 960 interpolated image to 2,560 x 1,960 pixels and transfers this up then that's the image size delivered. Quality is a different matter of course.
    The difficulty in comparing these kinds of things is that the image sensor is a key factor in the "zoom" resolution and therefore the simplistic 100x zoom scale does not provide enough information because if both sensors are 640 x 480 (ish) but one is twice the size of the other, then what should the reported "zoom" level be? This is where comparisons such as these in this video are so useful as they show the actual results side-by-side

    Those high end microscopes are really nice.
    For some of us, however, we don't have large labs to work in.
    My work bend is very small, so a large scope was out of the question.
    Back in 2017, I ended up buying a A1-N002 (Andonstar ADSM201) HDMI 1920x1080 scope.
    The screen is tiny and really not worth using it that way, but it has HDMI and I have that connected to a 24" monitor. The image is excellent.
    It brags a 300X magnification, but the "zoom" is only adjusting it up or down on its stand. LOL
    But the focus ability of this thing is really good, so I can get very close to my PCBs, but the sacrifice is that the lens is very close.
    This one was worth it for me as its footprint is very small.

      Used Andonstar ADSM201 for a while. It definitely was nice scope, but unfortunately with very little observable area. Good for phone and small circuit board repairs. But pain in ass when you had to deal with laptop motherboard due to lack of space at small base of ADSM201. Small distance between object and lenses also prevented working with larger boards. Due to that I was forced to purchase better and more expensive scope.

      But, I solved that problem.
      What I did was to fir swing the shaft, with the gear teeth, around so it's now towards the back.
      Then, I mount this on a shelf about my work area, "upside down.' Meaning, the "foot" part is on the shelf, the shaft faces down and the camera is now mounted on that.
      So the camera is now looking at the bench.
      The foot part, which is on the top shelf at the edge, I put a big washer with rubber screwed into the shelf, right at the far edge of the foot. This is to support it so that camera won't fall down.
      I hope I explained that clearly. LOL
      The point is, now I can adjust the camera up and down for a much wider view. I can easily use it now to view larger boards like PC motherboards, TV boards and the such.
      If I do need to get super close, I then just put the work (board) on a riser so that it's closer to the camera.
      I've used this for years in this position and it's just fine.
      Of course, if I had more space and if I was doing more work in my lab, then I would buy a larger format one with the dual arm and remote zoom, focus etc.

    With this kind of digital microscopes the magnification is practically a meaningless number: marketing department can play with the numbers and make it the higher they want, even if the actual details captures by the optics+sensor stay pretty poor.
    Light intensity and uniformity may also make a lot of difference: I bet that if you manage to get the illumination of the top level microscope mounted on the cheaper ones, the chip images will improve considerably.
    A more meaningful evaluation is resolving power: roughly speaking, the ability to capture and separate fine details. That's where you may find the bigger, and most significant differences among cheap and top level microscopes. That's what the test microscope glass with 0.01mm lines is for, though an even finer grid may be needed to actually pin the magnitude of the differences.
    To be fair, even the cheapest microscopes performed pretty decently (for the money) on the test glass. 0.01mm grid lines were well separated, and quite sharp (at least, the difference is not that much evident on a YT video). A finer test glass should make their limitations much more evident, but stability and light looks like their main limiting factor, nit the optics+sensor chain. Anyway, considering that one can use them lighthearthedly on the outside, in rough environments, connected to a smartphone, they may still be an interesting tool for many things.

    2) Wired USB to latptop/tablet device
    3) Wired HDMI
    Dual-lens for seeing depth.. and a large Field-of-View would also be nice. Unfortunately, the ones I've seen are very expensive, presumably because they have way too much zoom (130x-180x lens), or come with their own 10" display, or gimic features like remote-control, etc.

    Quick question: I have a c-mount type digital microscope and I want to buy a barlow lens that will help me see a wider viewing range. I want to see more components on the board. Should I buy the 50x or 75x from a height of, say, 2 feet? By the way, this is a great review! so extensive. 👍

      Do you mean 0.5x and 0.75x? Generally speaking the higher magnification, the closer you need to be to the work piece to focus. But it is also going to depend on other parts of your microscope. A 0.5x will give you half the magnification and presumably double the working distance? Assuming you aren't currently using a barlow that modifies your magnification. Although I could be wrong on that and maybe the working distance doesn't scale linearly with the magnification.

    I actually really did enjoy watching this video. Although not all that much interested in the micro techno anymore because it's just a little bit too expensive to do it right that is. Your microscope is awesome, the one you use. I'm pretty sure it's a little costly compared to all those that you were looking at. But I did really appreciate this video it did help me decide whether if I wanted to do this or not. Although I am into the hardware technical computer stuff, I am just not into the microwave hardware anymore. Thank you very much for that, by the way. It is absolutely truly worthwhile watching this video for many reasons.

    Really funny I received one two weeks ago and used it two days ago.
    It helped me look at my failure in 480p x50 zoom. Nice

    Excellent video. I have the Bysameyee microscope; when I zoom in with the wheel there are 2 different focus points, one with a lower magnification and one with a higher one. Is it possible you didn't scroll to the higher one? I don't know much about any of this, please excuse the terminology 😅

    great that someone can actually test to the bone this things so we, dreaming of getting cheap and better than real microscopes, can make decision to waste money one or other way 🙂
