Stemi 508 Compact Stereo Microscope
- Product SKU: ZE-STEMI508-A
- Category: Microscopes, Microscopes & Cameras, Stereo Microscopes, Zeiss
Stemi 508 is a robust and easy-to-use stereo microscope with 8:1 zoom (from 6.3x to 50x) and integrated LED illumination (brightfield and darkfield). It is ideal for routine checks of wafers molds, masks and microfluidic chips.
Observe your samples in real 3D, and document your research easily.
Darwin Microfluidics selected the most suitable configurations for microfluidics applications.
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.
- 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.
