Stemi 305 – Your All-in-One Instrument with Integrated Lighting and Documentation

The Stemi 305 is a compact Greenough stereo zoom microscope designed for biology education, laboratory work, and industrial production environments. It features a 5:1 zoom system and allows you to observe samples in clear three-dimensional detail with strong contrast—without requiring prior sample preparation.

This versatile microscope includes long-lasting LED illumination for both reflected and transmitted light. It also offers extensive documentation capabilities. You can choose between a traditional phototube compatible with ZEISS microscope cameras or an integrated 1.2-megapixel WiFi camera that enables multiple microscopes to connect and share images wirelessly.
