Description
Plan microscope objective 100 x / 1,25 (oil), spring-loaded is a plan-corrected oil-immersion objective for 100× microscopy at a numerical aperture of 1,25. Plan optics support a flatter field of view for observation across the image plane. The spring-loaded front assembly helps protect the lens and the specimen during focusing. Supplied as 1 pc in the microscopy accessories range, it is intended for instruments that accept this magnification, aperture and oil-immersion format. The OBB-A1239 unit from manufacturer Kern follows the stated plan 100 x / 1,25 (oil), spring-loaded specification. Net weight is 0,30 kg and gross weight 0,60 kg according to the packing data. Compact outer dimensions (height and depth 0,04 m, width 0,065 m) ease storage beside other nosepiece components. Laboratories select this objective when replacing or extending an existing set and when optical parameters must match the host microscope. Confirm mechanical thread and tube-length compatibility before installation so the plan oil-immersion performance is fully utilised in routine laboratory and teaching work.

Questions about Microscope Objective KERN OBB-A1239
What is this article?
Microscope Objective KERN OBB-A1239 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.
