The SMZ171 zoom stereo microscope is the newest edition to Motic's popular SMZ microscope family. Similar to the SMZ-168, the SMZ-171 also features new-generation optics, more efficient LED illumination and ESD-Safe compatibility. Destined for advanced biomedical and materials science applications, the SMZ171's optical performance will satisfy the most rigorous demands from professionals in biology, medical research, high tech manufacturing and more. The modern design and available ESD-safe compatibility make this platform ideally suited for quality control work in semiconductor cleanrooms and other sensitive electronics environments.


The Greenough optical system is built around new-generation lead-free optics offering sharp, three-dimensional upright images through a 45-degree inclined head which rotates through 360 degrees. Ergonomic 10X FN 23 widefield high eyepoint eyepieces are set in a Seidentopf movement with 54mm-76mm of interpupillary adjustment and +/- 5 degrees of dioptric range. Dual zoom control knobs operate a 6.7:1 zoom ratio for 7.5X to 50X total magnification in just one rotation. Five defined click-stop positions within the zoom range allow for exact reproduction of magnification, a necessary requirement for precise measurements. The standard working distance of 110mm (4.3") offers generous space for manipulating specimens under observation, and it can easily extend to 300mm with an optional 0.3X Auxiliary Barlow lens.

Focus & Illumination

Dual rack and pinion focus controls are conveniently positioned and feature tension adjustment for responsive and precise movement. For added flexibility, choose between natural illumination, or variable intensity, 3W LED incident and transmitted illumination. ESD-Safe focus and illumination is optionally available.


Choose between an economical plain stand or large working area stand with 3W LED transmitted illumination from an integrated 110V - 240V universal power supply. Both options feature a 32mm vertical post, 110mm working distance and a wide surface platform with chemical-resistant finish, black/white or frosted stage plates and 2 included spring clips. An ESD-Safe configuration is optionally available - please call for pricing.
