I don't know if a high magnification microscope like you're describing is available with a zoom function, as lower gain units are, but if there is a zoom function available, get it.OK - thank you this sounds like a classical microscopeI am personally familiar with much lower gain instruments, for inspecting and assembling electronic circuits using surface mount devices. That kind of microscope would use about 7X to 20X zoom magnification.yes but modern electronics get smaller and smaller - factor of 10x is not good.If you want to record, there are optical microscopes with a "third eye" where a camera can be installed, and the camera could be an electronic camera with output to a computer.this is also a good ideaWhen you know for sure what kind of scope you want, look to eBay or a similar source--microscopes are quite expensive! --doug, retired RF EngineerOne thing I would like to use it for is electronics and another thing is for the children that are in school. So I wouldn't spend too much for professional optics (lenses) that are indeed quite expensive, but I may consider the other options you mentioned. I am also kind of reserved when it comes to modern things. They usually sell you some crap made in china. thanks
If you aren't concerned about high quality then this might be of interest.
Jiusion 40 to 1000x Magnification Endoscope on amazon for about $22. Best of all it works on linux! No drivers needed on Debian.
to see how it works.
just use mpv:

[autoconvert] Converting yuyv422 -> yuv422p

the actual device may be different. My system had video0 and
