This is a stereo microscope with a variable 144-LED illuminator. The microscope offers super widefield optics, 7X-90X zoom magnification power and large working distance. The LED illuminator is intensity- and direction- adjustable. In other words, you can adjust the intensity and change the direction of the illuminating light. This microscopy unit is a perfect system for industrial inspection applications. It is an ideal instrument for gemologists, manufacturing engineers, and anyone in semiconductor and electronic industries. It is also the right microscopy system for biological laboratory applications that require low heat release. It is made by the same technicians and on the same production line that makes optical instruments for Leica, Zeiss, Nikon and Olympus. This microscope is brand new in factory sealed boxes. Its retail value is $1,700.
