Stemi 305

Your All-in-one Device. With Integrated Illuminations and Documentation, too.

Stemi 305 is your compact Greenough stereo microscope with 5:1 zoom for biological education, labs and industrial production environments. Observe your samples as they are: three-dimensional and crisp in contrast - no preparation required. Profit from this easy-to-use microscope, where everything is integrated: long-living LED illumination for reflected and transmitted light and documentation, too. Choose between the conventional phototube to have access to all ZEISS microscope cameras or the integrated 1.2 Megapixel Wifi camera to connect several microscopes and share your images via WLAN.


Documentation is important for lab work, essential for industrial inspection. In the classroom your ability to acquire and share images is a key resource for vivid, exciting science courses. Stemi 305 comes with two options for documentation:


Choose Stemi 305 trino with a phototube for access to any ZEISS Axiocam microscope camera and free ZEN lite imaging software. The fixed 50/50 division is optimal for life demonstrations: your students or customers can follow your microscopic work life on the monitor.

Or opt for Stemi 305 cam ‐- a 1.2 Megapixel Wi‐-Fi camera and WLAN router are already integrated into the microscope body. You will enjoy its ability to stream live images from several microscopes to multiple iPads. In “Access point” mode each Stemi 305 cam creates its own WLAN: up to six iPads can connect directly to the integrated camera and display its live image using the iPad imaging app Labscope. To create a high quality digital classroom, enable “Add to existing WLAN” mode and connect several Stemi 305 cams to the same digital network.

The iPad imaging app Labscope displays the live images of all Stemi 305 microscopes in your network to each connected iPad. With one touch you can look at each student's results. It's easy to snap an image, add annotations and measurements, and save it – or export it directly to your server.
