Kern OBN 13 Biological Transmitted Light Microscope

The OBN 135 transmitted light microscope from Kern is designed for particularly demanding applications. The 3 W LED illumination and the professional Köhler illumination ensure optimal illumination of the specimens. The five-fold lens revolving unit is equipped with high-quality Infinity Plan objectives, so that the entire specimen is displayed sharply in the 20 mm field of view. In addition to the standard objectives, an objective with 20x magnification is also included.

The tube is equipped with 10x eyepieces and diopter compensation on both sides, making it particularly suitable for spectacle wearers. Optionally, a camera can be connected to the trinocular tube via a C-mount adapter, to allow documentation and display of the examined objects.

The OBN 135 is particularly suitable for use in hospitals, laboratories and universities for examining challenging specimens such as living mammal cells, bacteria or tissue samples.
