Your Stereo Microscope with Integrated Illumination & Documentation

Stemi 508 is your robust all-rounder for everyday lab work in biology or industrial inspections. Observe, document and share your samples exactly as they are: rich in detail, sharp in focus and free from distortion or color fringes..

Profit from an easy-to-use microscope, where everything is integrated: long-life LED illumination, reflected and transmitted light and documentation.

Highlights

  • ZEISS Stemi 508's apochromatic zoom optics and efficient stray light suppression give you a crisp three-dimensional image, distortion-free, without color fringes.
  • Thanks to the low viewing angle of 35°, Stemi 508 is more ergonomic than any other Greenough-type stereo microscope.
  • Everything integrated into Stemi 508 stand K – no additional cables or boxes.
  • Easily select and mix the integrated LED illuminations (vertical and oblique reflected light, so as transmitted light).
  • Large working distance (92 mm) and object fields – examine whole samples and chips.
  • LED segmentable ring light for shadow free and homogeneous ring illumination and oblique light segment illumination: half circle, quarter circle, two-spot
  • LED spot K, zoomable and height adjustable, for oblique and grazing light illumination with strong shadow
  • Additional front optics available for varying the working distance and the object field. 

Designed for Your Applications

  • Observe and identify biological samples in the classroom, and in the lab.
  • Inspect your molds and chips before and after microfabrication to identify possible defects.
  • Observe most of your chip with a large field of view of 36 mm and zoom in for more details.
  • For even larger samples, add interchangeable optics and observe an area of up to 122 mm.
