Briefly about the Inskam 307 dissected microscope.

I got tired of taking pictures through a phone with a lens, so I decided to buy a microscope for this purpose.
Well, since I bought it, of course I took it apart.

The name was found in the instructions, Inskam-307, there is an official website, where other models are available and it seems like a link to the software, but I could not download it, although there is an impressive instruction in the form of pictures, like enter the url correctly. The url itself is not available anywhere, you must enter it manually.

Judging by a cursory measurement with a ruler, the actual maximum magnification is 20x 47x, the minimum is 5x
At first I thought it was 20x, but it turned out that the lens wheel was jamming, after disassembly, it seemed to turn better and was able to turn it to the maximum, it turned out about 47 times, like the twin brother from another review mysku.club/blog/china-stores/78040.html.

When connected to a computer, it gives the only option 1280×790, 25 frames per second.

Color rendition seems to be normal, the photo is saved to the USB flash drive in the same way as it is seen on the screen and is quite similar to the original.
By the way, for some reason I didn’t want to see and format a 4 gig flash drive, but the benefit was 2 gig at hand. Photos in the size of a megapixel will fit dofiga there.
The backlight copes with the maximum zoom, and at the minimum it looks a bit dark.
the round table is removable, there is a square hole under it, probably there are variations with lower illumination.

An example of a fragment of a figure with 100r. at maximum zoom through the program from the computer:

When connected with a flash drive, it is defined as DV15 DEVICE_V1.00, camera USB\VID_1224

The same place, but photographed on a flash drive of the device, very tight buttons and it is impossible to take pictures without “shaking”
when you press the buttons, the flimsy case walks and the picture is blurred, somehow I made a more or less clear photo:

But this is expected, I will make a remote button on the wire.

The internals are roughly in line with other microscopes with a similar adjustment principle.
The backlight is soldered to two studs, current leads, which are the guides of the lens.
The lens is tight, despite the lubrication, it is difficult to twist with one finger.
