| Aug 21, 2020 at 17:32 | comment | added | JRE | @i336_: I don't think the magnification is as high as you want, but it is cheap. You can partially disassemble a Logitech C270 web cam. From the outside, it has a fixed focus, but there is in reality a focus knob inside the housing. You can focus it down to about 1 cm, and get very detailed pictures. It may not fit your needs, but it is cheap and readily available. Since I have my doubts about how much magnification you really need, I'm just making a suggestion in a comment. | |

| Aug 21, 2020 at 6:26 | comment | added | joojaa | Notes: a inspection camera uses a telecentric lens. A telecentric lens has no, or allmost no perspective so measurements are easy. In way a inspection camera is usually a digital replacement to a optical comparator. But sounds really like you are looking for a optivisor As suggested by user94588. You should have asked this on engineering | |

(And if you move it, do specify if 1mm is the largest detail or the smallest... difference between a jeweler working on a ring setting 1mm stones vs a pencil lead carver (really a thing) working on a pencil lead that's only 1mm wide at largest.) | |

| Aug 20, 2020 at 16:48 | comment | added | J... | You might also consider reading a decent tutorial on designing an imaging system. I think you need some background learning to fill in the blanks. A lot of your "why" questions can't really be answered without a lot of physics and optics - more than are reasonable to include in an answer here. | |
| Aug 20, 2020 at 16:42 | comment | added | J... | Really, your best bet is to get a cheap kid microscope on Amazon and get a cheap smartphone adapter for the screen. For $200 you won't get much else. For a job like this (closup manual work) I'd usually recommend a binocular workstation like the Leica MZ9.5, but that's a $3500 tool... | |
| Aug 20, 2020 at 16:37 | comment | added | J... | This is basically a shopping question, and we have zero idea what the application or requirements are. Is colour reproduction important? What real resolution do you need to achieve? How much light do you expect to have? What exposure time restrictions do you have? This is a poor question not only because it's a shopping question, but because you haven't told us anything that will allow us to help you. | |

Older digital cameras with HDMI outputs can have totally unacceptable lag. The claimed Hz may be high but there STILL may be a large lag so you pretty much have to try it. | |

| Aug 19, 2020 at 18:55 | comment | added | Oleg Lobachev | Taking an inexpensive / used / sorted-out because of age microscope and adapting a real camera to it (DSLR, mirrorless, etc.) might be the bargain solution, if you already have a camera and can get your hands on a cheap microscope. You basically would want really old, but real research / production tool, rather than a new toy. Now, a lot depends on the hardware (duh), but typically you would have either the T2 mount (which is easy adaptable to any real camera) or you'd need to look up the rear focal distance and order / custom produce an adapter from microscopic tract to the camera. | |
| Aug 19, 2020 at 18:13 | comment | added | Mast | Can you tell us what you're actually trying to magnify? I have some experience with putting a coin full-screen on a 24" with decent resolution to see plenty of the details from a hacky 50$ set-up. With an extra lens, I'm sure 2mm full-screen is possible, but you'd really want an adjustable focus. | |

| Aug 18, 2020 at 17:01 | comment | added | Old Uncle Ho | Something you'll run in to when you increase magnification is the proximity of the front of your lens to your subject, 'working distance.' The higher the magnification, the smaller it usually becomes. Second thing is depth of focus: this is the range of (near to far) focal distance of, say, 'good, usable' of your subject. If the subject is planar, like a stamp, most of the field can be in focus at once. Add depth, even a very small amount and little will be in focus. Then there's ability to finely control focal distance, and lens quality may be too low for your needs...? | |
