This zoom stereo trinocualr microscope system includes a 3.5X-90X zoom stereo trinocular microscope with dual lights - reflected and transmitted plus 144-LED bright white shadowless ring light. This microscope can be used for inspecting insects, coins, stamps, rocks, gems, jewels, PCB, electronic chips, circuit boards, watch parts, leaves, powder, mold. With the 0.5X barlow lens, the working distance can be as long as 6-1/2" (165mm), and the field of view can be as large as 2-3/8" (60mm) in diameters. The optional 2X auxiliary lens can be used to increase the total power to 180X which is good for some precision instruments. An optional USB 2.0 digital camera can be connected to a computer and the free software coming with it can be used to capture pictures and videos even do some simple measurements.
