ZEISS Stemi 508, Documentation Version, Trinocular 100:100, Greenough, Working Distance 92 mm, 10x/23, Zoom 8:1 (0.63x–5.0x) (54509, 435064-9020-000)

The Stemi 508 is a compact and highly reliable Greenough stereo microscope developed for intensive laboratory and industrial use. Its apochromatic optics deliver excellent image contrast and precise color accuracy. Designed for heavy workloads, this microscope provides a large object field of up to 36 mm, allowing complete samples to be viewed in a single field of vision.

With an 8:1 zoom range and magnifications up to 50x, the Stemi 508 ensures detailed observation of fine structures. When combined with interchangeable optics, it enables viewing areas up to 122 mm in diameter. The ergonomic 35° viewing angle supports a comfortable working posture, even during long periods of observation.

This model allows both precise visual inspection and professional documentation of specimens, producing sharp, detailed images without distortion or chromatic aberration. It is a robust and versatile solution for daily laboratory tasks and industrial inspections.
