KERN Stereo Binocular Microscope

The KERN OSF-4 is a very robust, stable and easy to use stereo microscope. Their mechanical stand makes them particularly stable. Models OSF 434 and OSF 435 are provided with 3 objectives each and an additional fine focusing knob for precise focusing. In addition to its very good optical properties, its large working surface offers the best possible ease of use in this class.

This model is optimally suited for schools, workshops and training establishments. The model-dependent LED incident and transmitted illumination unit reliably ensure good illumination at all times. The multitude of objective combinations and eyepieces are all you can wish for. The eyepieces are fixed in the tube to protect them against loss or damage. One of the central features of this variable and simultaneously robust series of micro- scopes is the stable and precisely adjustable mechanism. This is underlined by the functional and ergonomic design
