Description

ZEISS Stemi 508 with Stand M LED & K LED Illumination – Flexible Stereo Microscope for Lab & Research

The ZEISS Stemi 508 with Stand M LED and K LED Illumination is a high-precision stereo microscope for laboratories, education, and research.
With its apochromatic Greenough system, 8:1 zoom and excellent color reproduction, it delivers brilliant, high-contrast 3D images.

The large, robust Stand M LED offers a particularly large working area, an extended column height, and an upgradeable transmitted light unit.
The integrated M LED transmitted light unit allows for brightfield, darkfield, and oblique illumination via a rotatable and displaceable mirror system.

The modular K LED illumination – spot, double spot, and segmentable ring light – offers maximum flexibility in incident light for a wide variety of samples.
Additionally, the Stand M LED has 3 memory buttons that can store and recall light combinations.

A system for professional work environments where image quality, flexibility, and ergonomics are paramount.
