Description
Infinity plan microscope objective KERN OBB-A1297 is an infinity-corrected plan objective designed without cover-glass correction for applications that need a comparatively large working distance at high magnification. It delivers 80× magnification with a numerical aperture of 0,8 and a working distance of 0,85 mm, and uses a spring-loaded mount to help protect optics and sample during focus travel. The cover-glass-free plan design supports flat-field imaging for materials science, metallography and industrial inspection where specimens are examined without a coverslip. Extended free working distance relative to many high-power dry lenses aids observation of structured or bulk samples. Provided as a single piece from manufacturer Kern, the objective is intended for compatible infinity optical systems in laboratory and quality-control environments. Spring loading reduces the chance of hard contact when working at short clearances. Laboratories equipping infinity-corrected microscopes can employ the OBB-A1297 for brightfield and related reflected-light methods that benefit from high magnification, plan correction and cover-glass-free optics.

Questions about Microscope Objective KERN OBB-A1297
What is this article?
Microscope Objective KERN OBB-A1297 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.
