The KERN OBE 131 monocular microscope is a replacement for the OBE 111, and stands out for its sturdy construction and ergonomics. An integral storage compartment at the back allows the power cable to be stored neatly out of the way. A fully dimmable 3W LED guarantees bright illumination from below (transmitted light), and a focusable 1.25 Abbe condenser with aperture diaphragm is included as standard, for provision of optimum concentration of light for the sample being studied. Height adjustment of the fully featured mechanical stage is carried out using coaxial coarse and fine focusing knobs on both sides, for quick and easy focusing. The 40x and 100x objectives are spring loaded. Comes complete with protective dust cover and eye cups.
