ZEISS Stereo zoom microscope Stemi 508 EDU-Set, bino, 6.3x-50x, Transmitted light (50213, 495009-0006-000)

ZEISS Stereo Zoom Microscope Stemi 508 EDU-Set, Binocular, 6.3x–50x, Incident and Transmitted Light (50213, 495009-0006-000)

The Stemi 508 is a compact and durable Greenough stereo microscope designed for demanding educational, laboratory, and industrial applications. Its apochromatic optics deliver outstanding image contrast and accurate color reproduction. Built for intensive daily use, this microscope offers a large object field of up to 36 mm, allowing you to view entire samples at once.

With an 8:1 zoom range and magnifications up to 50x, the Stemi 508 provides detailed observation of fine structures. When combined with interchangeable optics, it enables observation of fields up to 122 mm in diameter and magnifications from 2x to 250x. The ergonomic 35° viewing angle ensures comfortable operation even during extended working sessions.

This microscope allows precise observation and documentation of specimens with sharp focus, high detail, and no distortion or color fringing. It is a reliable all-round instrument for laboratory work and industrial inspection tasks.
