ZEISS Stereo Zoom Microscope Stemi 305 MAT, Trinocular ESD, Greenough, Working Distance 110 mm, 10x/23, 0.8x–4.0x (48747, 491903-0007-000)

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

The Stemi 305 is a compact Greenough stereo zoom microscope with a 5:1 zoom ratio, developed for education, laboratory environments, and industrial production. It provides clear three-dimensional visualization with high contrast, allowing samples to be observed without preparation.

This user-friendly system includes long-life LED illumination for incident and transmitted light, as well as comprehensive documentation options. Users can choose a conventional phototube compatible with ZEISS microscope cameras or an integrated 1.2-megapixel WiFi camera for wireless image sharing between multiple microscopes.
