Description
OBL 137 transmitted light microscope, trinocular, incl. eyecups and dust cover
Lab Line. Flexible and versatile transmitted light microscope (bright-field) with infinitely corrected optics. Specially designed for laboratories that work with translucent, low-contrast, challenging specimens (e.g. living mammalian cells, bacteria, tissues).
- The infinity corrected optics ensure top-class image quality
- The 4-slot lens revolver is fully equipped with four high-quality, infinitely corrected E-PLAN lenses (4x/10x/40x/100x) with improved edge definition
- The 1.25 Abbe condenser with aperture cover, with its height-adjustable focus and fixed precentring, and the field diaphragm enable easier Köhler illumination and thereby provide simple and optimal illumination of the specimen, with no negative flare effects
- The mechanical cross table ensures fast working and positioning of the specimen. It features a coaxial coarse and fine focus drive fitted on both sides for adjusting the height and focussing on the specimen
- With strong, infinitely dimmable 3 W LED transmitted light illumination
- Dark field condenser to increase contrast of small, unstained structures
- 100x lens (planachromatic, spring) with water immersion
With trinocular head for mounting a microscope camera on the phototube using C-mount adapter. Please order C-mount adapter separately.

Questions about OBL 137 transmitted light microscope, trinocular, 1 unit(s)
What is this article?
OBL 137 transmitted light microscope, trinocular, 1 unit(s) is the article on this page. Luminix Health distributes KERN for laboratory use. It sits in Digital & USB microscopes, inside Microscopy & histology, in Lab instruments.
A digital or USB microscope is a camera with optics, useful for inspection and for a quick shared image. It does not replace a compound microscope when the method needs a stated numerical aperture and a fluorescence filter. Magnification claims on these are often a screen magnification, not an optical one.
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.
