This is a trinocular 3.5X-180X zoom stereo microscope on a versatile double-arm boom stand with a 144-LED ring-light and 3MP camera. The trinocular head has 30mm super widefield high-eyepoint eyepieces, providing a large field-of-view. It offers an expansive range of magnification, from 3.5X to 180X, as well as a long working distance. The versatile double-arm boom stand allows you to turn the microscope head around three different axis (x, y, and z). You can point the microscope head in ANY direction desired. The LED ring-light provides even, cool illumination. The 3MP camera captures both still images and video, and the included software provides an array of measuring tools for inspection applications. This microscope is an ideal instrument for gemologists, engravers, collectors, manufacturing engineers and anyone in semiconductor and/or electronic industry.
