Description
Bertrand lens KERN OBB-A1121 is a microscopy accessory configured as a built-in, centerable Bertrand lens for compound optical systems. It supports laboratory workflows in which the intermediate image plane must be inspected or aligned with controlled lateral adjustment. The centerable construction allows the optic to be positioned precisely within the tube path, which is useful during setup, teaching demonstrations, and routine checks of conoscopic observation conditions. Supplied as one piece, the unit has a net weight of 0,20 kg and a gross weight of 0,50 kg, with compact packaging suited to secure handling of optical components. This accessory from manufacturer Kern sits in the microscopy accessories category and is intended for integration into compatible microscope platforms rather than as a stand-alone instrument. Laboratories can use it when specifying or completing an optical train that calls for a dedicated Bertrand lens with centering capability. Physical packaging data reflect a small-format shipment profile appropriate for spare parts and modular microscope upgrades in research, education, and quality-control environments.
This article is part of Microscope objectives, eyepieces & optics, in Microscopy & histology.

Questions about Lens KERN OBB-A1121
What is this article?
Lens KERN OBB-A1121 is the article on this page. Luminix Health distributes Kern for laboratory use. It sits in Microscope objectives, eyepieces & optics, inside Microscopy & histology, in Lab instruments.
An objective makes the resolution. Magnification and numerical aperture are the two numbers, and the tube length or the infinity correction has to match the microscope. An eyepiece mostly enlarges the image the objective already resolved. A mismatched objective does not become sharper by zooming.
A light microscope forms an image with glass lenses and transmitted or reflected light. A stereo microscope is the lower-magnification instrument for dissecting and for looking at a surface. Fluorescence needs a light source and filters matched to the dye. Histology is the preparation that makes a tissue readable: fixation, a cassette, a section, a stain. The objective's magnification and numerical aperture decide the resolution. The slide and the cover glass decide whether the section sits in the focal plane. Stains and dyes as substances are identified on PubChem. Papers on the methods are on PubMed.
