The KERN OBN 132 is an excellent and stable laboratory microscope for all common routine applications for impressive images. These trinocular microscopes are equipped with wide field eyepieces with a large field of view, diopter adjustment on both sides and infinity corrected plan achromatic objectives as standard.

The professional Koehler illumination is easily adjustable. It includes an adjustable field diaphragm, and a central and height adjustable Abbe condenser with adjustable aperture diaphragm. This provides impressive images in both bright and dark field applications.

A nosepiece for up to five objectives and a large stage are provided as standard. The following optional accessories are available: A variety of eyepieces, objectives, a complete polarisation kit, a swing-out condenser, diverse phase contrast sets, complete HBO and LED fluorescence kits, and more.

One of the central features of this highly variable and simultaneously robust series of microscopes is the stable and precisely adjustable mechanism. This is underlined by the functional and ergonomic design.
