Motic SMZ-172 Series 0.75x to 5.0x Binocular Stereo Microscope

Stereo Zoom Microscope for Scientific Research, Biology, and Environmental Monitoring

High-resolution Greenough optical system designed for detailed three-dimensional study of biological and natural samples in the laboratory and field.

The Motic SMZ172 Series is a high-performance Greenough-type stereo zoom microscope designed to deliver superior stereoscopic images in scientific and environmental research applications. It is characterized by high resolution, true-to-life color reproduction, and a wide field of view that provides a strong three-dimensional effect.

This precision optical system features a 1:6.7 zoom ratio with continuously adjustable magnification from 0.75X to 5.0X in its standard configuration, reaching up to 200X with optional accessories. Its ergonomic design incorporates a 45-degree viewing angle and an eyepoint height of 370 mm to reduce physical fatigue during long working hours. Furthermore, its versatile reflected and transmitted illumination allows for multiple lighting modes for detailed observation in biology, botany, entomology, marine biology, geology, paleontology, and earth sciences.
