AmScope SM-1TSX-144S 3.5X-45X Dissecting Trinocular Zoom Stereo Microscope with 144-LED Light

This is a trinocular stereo microscope with a 144-LED compact ring light with a built-in dimmer. The microscope has a super widefield optical system that provides a large zoom magnification power (26:1) and a large working distance (8", 200mm). The trinocular port uses the third port for camera capabilities, or a third party to view as well, giving you the remaining two ports to view your specimen. The 144-LED ring light has a compact design with a built-in dimmer, providing cool, even and bright LED illumination. This microscopy system is an ideal instrument for manufacturing engineers, lab technicians, gemologists, circuit board inspectors, and anyone in electronic and semiconductor industries. It is also the right microscope for biological laboratory applications that require low heat release.
