Description
Infinity PH plan objective 20× KERN OBB-A1391 is a phase-contrast plan objective for infinity-corrected laboratory microscopes. At 20× magnification it bridges survey and detail views, supporting phase-contrast examination of cells and other low-contrast samples that benefit from a flatter field. The objective is supplied as one piece, with a net weight of 0,30 kg and a gross weight of 0,60 kg. Outer packaging is 0,065 m wide, 0,04 m deep and 0,04 m high, equating to a packaging volume of 0,000104 m³. Offered by manufacturer Kern as microscopy accessory hardware, it is intended for compatible infinity optical systems in research, teaching and routine analytical laboratories. The optic complements existing PH plan sets where a mid-range 20× lens is required for structured observation without redesigning the stand. Country of origin is China. Compact packing and defined weights simplify inventory handling for facilities that maintain standardised infinity phase-contrast objective kits across multiple workstations and teaching benches.

Questions about Infinity PH-Plan-objective KERN, OBB-A1391
What is this article?
Infinity PH-Plan-objective KERN, OBB-A1391 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.
