Stemi 305 Stereomicroscope – Zeiss
The Stemi 305 is a versatile stereomicroscope, ideal for teaching, quality control, dissection and magnifying. It offers a zoom ratio of 5:1 for magnifications of up to 40x, with a comfortable working distance of 110 mm. Its optical head can be configured as binocular or trinocular with 10X/23 mm eyepieces.
Available with a range of modular stands, it can be adapted to suit every need:
- Simple K stand: basic version, for use with an external light source.
- K MAT stand (industry): equipped with varied reflected lighting, a segmentable LED ring and ESD protection.
- K EDU stand (education): combining reflected and transmitted light, with transmitted light base and polarisation options, ideal for a digital environment thanks to the Stemi 305 camera and Labscope application.
- K LAB stand (laboratory): designed for advanced observations, including oblique brightfield, with multiple lighting sources (LED spotlights, double gooseneck, ring, tilting mirror).
With its many lighting options and ergonomic design, the Stemi 305 is a high-performance, adaptable solution for educational, industrial and scientific environments.
