Stereomicroscopes Stemi 305

Trailer Stemi 305
Stemi 305 is a compact Greenough stereomicroscope with 5:1 zoom. Equally suited to the biology classroom, research lab or on the industrial shop floor.

Observe samples as they are: in real 3D, distortion free and crisp in contrast, with no preparation required. Then images can be shared. Easy-to-use microscope, where everything is integrated: long-life LED illumination, reflected and transmitted light and documentation. For documentation images can be snaped simply with the integrated 1.2 MPx Wi-Fi camera and shared using Labscope, the iPad imaging app. Alternatively, a conventional phototube can be used to have access to all Axiocam cameras and free ZEN lite imaging software.
  • Everything integrated into Stemi 305 stand - no additional cables or boxes.
  • Stemi 305 microscope sets for education, lab and industry ensure optimised object illumination.
  • Easily select and mix the integrated LED illuminations (vertical and oblique reflected light, so as transmitted light).
  • Large working distance and object fields - examine whole living samples.
  • Shadow-free, homogeneous illumination provided by the vertical LED spot of Stemi 305 as well as the flexible alignment of the microscope with tilting arm stand U.
  • Integrated wireless camera and router option with Labscope - the iPad imaging app where you can create your own virtual classroom and share your images.
  • All Stemi 305 zoom bodies are equipped with an integrated vertical illumination to observe holes or cavities.
  • All LED illuminators K - even Stemi 305 cam with integrated camera - are powered by the electronics of stands K.

Illumination kits
Education kit:
  • Spot K LED, zoomable and heightadjustable for oblique, bright field and grazing light.
  • Flat transmitted light stand for bright and dark field (of stand K Edu), polariser / analyser equipment optional.

Laboratory kit:
  • Mirror based TL unit of stand K Lab to look at uncoulored, transparent samples in crisp oblique light.
  • Double arm gooseneck - for dissections in reflected light.
  • Optional: polariser / analyser.
  • Ergo hand rest for relaxed posture.

Industrial kit:
  • ESD safe by antistatic surface treatment of stand K Mat.
  • Segmentable ringlight to quickly find scratches, defects, residues.
  • Integrated near vertical spot to inspect e. g. drill or thread holes.
