Description
Transmitted light microscope KERN OBN 135 is a professional laboratory instrument that combines high optical quality with ergonomic design and true Köhler illumination for demanding transmitted-light work. A powerful, continuously dimmable 3 W LED light source feeds an adjustable field diaphragm and a centreable, height-adjustable 1,25 Abbe condenser with variable aperture diaphragm, delivering even, high-contrast illumination across the field. The large mechanical stage, fitted with bilateral coaxial coarse and fine drives, supports fast, precise specimen positioning and focusing. Modular accessories—including swing-out condensers, alternative eyepieces and objectives, colour filters, phase-contrast and dark-field condensers, simple polarisation units, butterfly tubes and complete fluorescence modules—allow the system to be configured for specialised workflows. Supplied complete with dust cover, eyecups and a multilingual operating manual (C-mount adapter required for camera connection), this model from manufacturer Kern is suited to haematology, urology, gynaecology, dermatology, pathology, microbiology and parasitology, immunology, wastewater analysis, oncology, entomology, veterinary work, water testing and brewery laboratories. Typical specimens include translucent, thin, low-contrast preparations such as living mammalian cells, bacteria and tissue sections.

Questions about Transmitted Light Microscope KERN OBN, 135
What is this article?
Transmitted Light Microscope KERN OBN, 135 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.
