Description
Achromatic microscope objective 4 × /0,1 is a low-magnification overview lens with numerical aperture 0,1 and a generous working distance of 18,6 mm. The long free distance simplifies specimen handling, scanning large fields and initial orientation on the slide before switching to higher powers. Supplied as 1 pc from manufacturer Kern, this objective is intended for compound microscopes in laboratory, teaching and routine analytical environments. Achromatic correction supports improved colour representation compared with simple lenses when surveying stained preparations or whole mounts. The 4 × /0,1 format is a standard first step on multi-objective nosepieces, providing context before medium- and high-magnification work. Net weight is 0,30 kg and gross weight 0,60 kg; packaging height is 0,04 m, width 0,065 m and depth 0,04 m, with a volume of 0,000104 m³. As a microscopy accessory, the OBB-A1111 unit fits workflows that need a reliable achromatic 4 × objective with 18,6 mm working distance for brightfield overview imaging.
This article is part of Microscope objectives, eyepieces & optics, in Microscopy & histology.

Questions about Microscope Objective KERN OBB-A1111
What is this article?
Microscope Objective KERN OBB-A1111 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.
