This is a compact Greenough stereo microscope, created for labs, biological education and industrial production environments. Without preparation required, one can observe the sample as it is: crisp in contrast and three-dimensional. 

Stemi 305 has an integrated long-living LED illumination for reflected and transmitted light and documentation. Those has a low energy consumption, stays cool, are noiseless and maintenance-free.




This model comes without additional cables and boxes. You just have to plug it in and switch it on, and the installation is done. It can be operated easily by untrained users also, because all you have to do is to illumiate the object, focus and then start snapping images. By choosing the integrated 1.2 Megapixel Wifi camera you can connect several microscopes and share your images via WLAN.
