Kern's OBS microscopes are specifically designed for use in educational environments, and are an excellent tool for enhancing science studies in primary and secondary schools, training establishments or simply for hobbyist use.

Easy to use with solid, reliable magnification capabilities, Kern's OBS range is easy to understand for students and provides them with the ability to see a wide variety of samples magnified.

The functionality of the microscope depends upon the model you purchase - the OBS101 is a single optic (monocular) scope with 0.65 condenser lens and a rotating aperture diaphragm disc for best concentration of light and illumination with minimal adjustments. The OSB104 and OSB 106 models have binocular-style viewers and come with a 1.25 Abbe condenser which is height-adjustable, allowing the focus on the object to be adjusted as needed.

All models in the series come as standard with a coarse and fine focusing knob on both sides for easy adjustments. OBS 101 and OBS 104 models have fixed, non-moveable stages for samples, while the OBS 106 model comes with a mechanical, moveable stage.

These microscopes are recommended for the study of translucent, thin, high-contrast, less complex samples such as plant tissue, coloured cells and parasites.
