The LED light source guarantees optimum illumination of the samples and also ensures long service life. The simple condenser lens with rotating aperture diaphragm disc on the OBS 101 ensures the best concentration of light and illumination of the sample.

The OBS 104 (RS 136-3476) and OBS 106 (RS 136-3477) models have an Abbe condenser which is height-adjustable and can therefore be focussed. And an aperture diaphragm, which ensures the best concentration of light. To focus the object, all models have a coarse and fine focusing knob on both sides. The mechanical angle table enables you to work with the samples and move them rapidly (only for KERN OBS 106).
