Description
Achromatic microscope objective 100 × /1,25 (oil) is a high-magnification oil-immersion lens with numerical aperture 1,25 and a working distance of 0,07 mm. The front is spring-loaded (retractable), which helps protect the optics and the specimen when focusing close to the slide. Supplied as 1 pc from manufacturer Kern, this objective is intended for compound microscopes used in laboratory, teaching and routine analytical work. Achromatic correction supports clearer colour rendering than simple lenses when viewing stained preparations under immersion oil. The 100 × oil format is typically selected after lower-power dry objectives have provided an overview, enabling finer morphological detail. Net weight is 0,30 kg and gross weight 0,60 kg; packaging measures 0,04 m height, 0,065 m width and 0,04 m depth with a volume of 0,000104 m³. As a microscopy accessory, the OBB-A1109 unit is suited to nosepieces that accept matching achromatic oil objectives with the stated magnification, aperture and spring-loaded design for everyday brightfield observation.
This article is part of Microscope objectives, eyepieces & optics, in Microscopy & histology.

Questions about Microscope Objective KERN OBB-A1109
What is this article?
Microscope Objective KERN OBB-A1109 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.
