Description

ZEISS Stemi 508 with Stand K Lab & K LED Illumination – Stereomicroscope for Demanding Laboratory Applications

The ZEISS Stemi 508 with Stand K Lab and K LED Illumination is a powerful stereomicroscope for research, education, and professional laboratory applications.
The apochromatic Greenough system with 8:1 zoom delivers detailed, high-contrast 3D images across the entire magnification range.

The Stand K Lab offers a precise and versatile transmitted light solution:
An integrated mirror transmitted light unit enables brightfield, darkfield, and oblique transmitted light – ideal for transparent, low-contrast, or sensitive samples.

Three combinable incident light options – spot, double spot, and segmentable ring light K LED – ensure maximum flexibility in sample illumination.
This set was developed for professional workflows in the lab and combines optics of the highest level with ergonomic operation.
