Description
Infinity Plan Semi Apochromatic microscope objective 20× KERN OBB-A1621 is a precision infinity-corrected lens for laboratory microscopy. This plan semi-apochromatic objective is intended for infinity optical systems and provides the 20× magnification step within the OBB series. Plan optics support a flat field of view, while the semi-apochromatic design addresses colour correction typical of this objective class, making the unit suitable for routine transmitted-light work, teaching setups and instrument configuration in life-science, materials and quality-control laboratories. The accessory is offered as a single piece for direct mounting on compatible microscope nosepieces that accept the corresponding infinity plan objective. Net weight is 0,30 kg and gross packaged weight is 0,60 kg, with compact outer dimensions that simplify storage, shipping and spare-part logistics. The OBB-A1621 model belongs to the infinity plan semi-apochromatic range from manufacturer Kern and is selected when a dedicated 20× plan semi-apochromat is required for system build-up, replacement or magnification expansion. Match tube length, cover-glass specification and illumination method to the host microscope so that parfocality and image quality remain within the instrument design. Category placement under microscopy accessories reflects its role as a modular optical component rather than a complete microscope.

Questions about Microscope Objective KERN OBB-A1621
What is this article?
Microscope Objective KERN OBB-A1621 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.
