Stemi 305 – Compact All-in-One Stereo Microscope

The Stemi 305 is a compact Greenough stereo microscope with a 5:1 zoom ratio, developed for biology education, laboratories, and industrial production. It enables three-dimensional viewing of specimens with high contrast and clarity, often without the need for sample preparation.

This system combines integrated LED illumination for reflected and transmitted light with flexible documentation options. Users can choose between a traditional phototube for ZEISS microscope cameras or an integrated WiFi camera version for digital classroom applications.
