Briefly about the Inskam 307 dissected microscope.
when you press the buttons, the flimsy case walks and the picture is blurred, somehow I made a more or less clear photo: Lens structure: 2G IR Foucus mode : manual An example of a fragment of a figure with 100r. at maximum zoom through the program from the computer:
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 backlight is soldered to two studs, current leads, which are the guides of the lens. The url itself is not available anywhere, you must enter it manually. Data format: JPG/AVI Judging by a cursory measurement with a ruler, the actual maximum magnification is 20x 47x, the minimum is 5x The same place, but photographed on a flash drive of the device, very tight buttons and it is impossible to take pictures without “shaking” 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. Frame rate: 30fps
Power supply: 1 * lithium battery, 3.7V, 1500mAh (included) When https://tonaton.com/s_44-residential-land-for-sale connected with a flash drive, it is defined as DV15 DEVICE_V1.00, camera USB\VID_1224 I got tired of taking pictures through a phone with a lens, so I decided to buy a microscope for this purpose. Focusing range: 0-40mm Interface: USB2.0 Image sensor: 2M fine quality image sensor But this is expected, I will make a remote button on the wire. Resolution: 1920*1080, 1280*960, 640*480 
the round table is removable, there is a square hole under it, probably there are variations with lower illumination. 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. Magnifications: 50x, 1000x Well, since I bought it, of course I took it apart. The internals are roughly in line with other microscopes with a similar adjustment principle. 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. Lens angle: 16° The lens is tight, despite the lubrication, it is difficult to twist with one finger. Micro TF card https://jiji.com.gh/car-parts-and-accessories/renault slot: support Micro TF card (not equipped with this unit) up to 32GB, including FAT, https://tonaton.ug/s_258-smoking-cessation-products FAT32 two file formats Display: 4.3 inches TFT panel, 16:9 The backlight copes with the maximum zoom, and at the minimum it looks a bit dark. Photos in the size of a megapixel will fit dofiga there. Aperture: F4.5 Light source: 8 LED lights (adjustable brightness)
