150 dpi snapshot of the world That’s why I just counted how many microns are in a pixel at some resolution. Three-position switch of the 8-diode backlight: off, dim and bright. : switchable backlight: allows you to view slides in transmitted light. At least in the water from the puddle one could clearly see 3-4 pixel balls that were floating in the water ( vd.reborn.ru/?a=watch

Portable USB 2.0 20X-800X 2MP Digital Microscope with 8-LED Illumination – Black

It was not badly made, but not without flaws: the clamp, when fully closed, did not hold the hinges tightly, it was necessary to grind down the clamp planes a little. 1) If there is autofocus in the camera, it is very weak. Which, of course, makes it impossible to focus on large objects. Hinge fastening is strong: there is no backlash. Let’s see… 3) Well, the most important question: what about the increase then? Based on this, I chose by magnification, but without fantasy. The description states that the magnification is x800… The child (more in me than mine 😉 ) really wanted a microscope. : well done I would assume that there is none. Here is a snapshot of 800*600 printed worlds at 150 dpi. Well, in short, the pros and cons: There is a button for taking a picture.
If everything is not sad with my calculations, then 1 pixel of an 800 * 600 image accounts for 2.3 micrometers. At the same time, it is quite convenient to adjust. Well, well… Adjusting the magnification is viscous or something … small movements occur with not very strong pressure, but it cannot be accelerated: the resistance increases. 0: the clip holds firmly, but after finishing with a file. As for optics, there are a lot of questions … My child wanted to see microbes in a puddle. I do not understand how you can calculate the magnification on a digital microscope? After all, if you take plasma as an “eyepiece”, then the increase will be generally fantastic. 😉 Thus, outside the highlight https://jiji.com.gh/51-microphones/mini ring, it is possible to focus on magnifications up to x200 and beyond x750. 2) The focus area floats when changing the magnification, but at the same time, in the area of ​​the drawn x200-x750 magnification values, the focus goes inside the backlight ring. But wet or greasy fingers will not work. In the beginning, about the microscope itself: -: focus most of the zoom range is outside : Zoom/focus control is smooth and comfortable.
