Stemi 305 – All-in-One Solution with Integrated Illumination and Documentation

The Stemi 305 is a compact Greenough stereo microscope featuring a 5:1 zoom ratio. It is designed for biology education, laboratory environments, and industrial production. The system enables clear three-dimensional viewing with sharp contrast, allowing observation of samples without prior preparation.

This user-friendly microscope includes durable LED illumination for both incident and transmitted light, along with comprehensive documentation options. Users can choose between a conventional phototube compatible with ZEISS microscope cameras or an integrated 1.2-megapixel WiFi camera, which enables multiple microscopes to connect and share images wirelessly.
