Description
Microscope filter KERN OBB-A3211 is a yellow optical filter accessory for laboratory microscopy, intended for use with the OBT-1 series. As a dedicated colour filter, it supports selective light conditioning in the illumination path, helping operators refine contrast and visual clarity when examining specimens under routine brightfield or related observation modes. Yellow filtration is a common choice where warmer spectral emphasis improves differentiation of structural detail without changing the core optics of the instrument.
This article is part of Light & fluorescence microscopes, in Microscopy & histology.
The unit is supplied as one piece, with a net weight of 0,10 kg and a gross weight of 0,20 kg, and ships in a compact package suited to accessory drawers and shared laboratory stock. Integration is straightforward on compatible OBT-1 setups, making the filter practical for teaching labs, research benches, and quality-control stations that standardise accessories across multiple microscopes. This filter from manufacturer Kern belongs to the microscopy accessories range and offers a simple way to expand illumination options on the designated platform. Consistent colour filtration across instruments helps maintain comparable viewing conditions from workstation to workstation, supporting reproducible daily workflows in educational and industrial environments alike.

Questions about Microscope Filter KERN OBB-A3211
What is this article?
Microscope Filter KERN OBB-A3211 is the article on this page. Luminix Health distributes Kern for laboratory use. It sits in Light & fluorescence microscopes, inside Microscopy & histology, in Lab instruments.
A light microscope looks through a thin specimen. A fluorescence microscope adds a light source and filters matched to a dye, so only the labelled structure shows. The filter set has to match the dye's excitation and emission. A bright-field microscope without those filters cannot do that experiment.
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.
