Stemi 305 Compact Stereo Microscope
Stemi 305 is a compact and easy-to-use stereo microscope with 5:1 zoom (from 8x to 40x) and integrated LED illumination (brightfield and darkfield). It is ideal for daily observations of a microfluidic chip.
Observe your samples in real 3D, and document your research easily.
Your Stereo Microscope with Integrated Illumination & Documentation
Stemi 305 is your compact Greenough stereomicroscope with 5:1 zoom. Equally suited to the biology classroom, research lab or on the industrial shop floor. Observe your samples as they are: in real 3D, distortion free and crisp in contrast, with no preparation required. Then share your images, whenever you want.
Profit from an easy-to-use microscope, where everything is integrated: long-life LED illumination, reflected and transmitted light and documentation.
- Everything integrated into Stemi 305 stand – 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 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.
Created for Your Applications
- Observe and identify biological samples in the classroom, and in the lab.
- Investigate the morphology of plant organs in your practical botanical work.
- Study worms, snails, spiders, frogs, crabs, eggs, and larvae for Zoology.
- Examine the fruiting bodies of large fungi to differentiate between edible mushrooms and inedible look-alikes.
- Perform detailed investigations or surgical procedures in your veterinary work with the shadow-free, integrated vertical illumination and flexible alignment of the tilting arm stand.
- Inspect or repair printed circuit boards in electrostatic protected areas. Profit from stand versions with ESD features.
- Easily detect scratches on metal surfaces using the segmentable ringlight
All Stemi 305 zoom bodies are equipped with an integrated vertical illumination to observe holes or cavities
