Bresser's Science ETD-201 8-50x Trino Stereo Microscope is a trinocular microscope with inclined stereo viewing and a third optical path for attaching C-mount cameras. It is designed to be a versatile multi-disciplinary professional tool that can be useful in academia, agriculture, industry, and forensics. Its optical system offers adjustable 8-50x magnification, top/bottom adjustable LED illumination, 4.1" working distance, and coarse focusing. The aluminum frame with a wide base ensures stability on your workbench or desk, while the tall back allows you to change the working distance for viewing larger samples. To deliver bright images to your eyes, this tool is equipped with incidental and transmitted dimmable LED illuminators, powered by a USB power adapter. Additionally, to emphasize or reemphasize certain features of your slides and to enable the transmitted illumination, the scope comes with two base plates: a glass and a black/white polymer plate.
