This compound microscope is designed for use in laboratories and vocational training applications.
Built to the highest standards, Kern’s OBF microscopes are equipped with adjustable field diaphragm plus pre-centred and height-adjustable Abbe condenser (with adjustable aperture diagram) to ensure high quality images in both bright and dark field applications.
Depending on the model you buy, the OBF will be supplied with various achromatic or plan objective lenses. Up to four of these can be fitted simultaneously into the microscope’s rotatable viewer, allowing you to instantly switch between each for the best view.
Every version of the Kern OBF also comes equipped with an illumination source; models OBF 121 and OBF 122 have a 6V/20W halogen light, while the OBF 123 comes with a 3W LED illuminator.
