Description
Achromatic microscope objective 4× / 0,1 is a low-magnification lens for laboratory brightfield microscopy. It provides 4× magnification at a numerical aperture of 0,1 and a working distance of 27 mm, supporting comfortable specimen clearance during scanning and overview work. Supplied as one piece with a net weight of 0,30 kg and a gross weight of 0,60 kg, the objective is suitable as original equipment, a spare or an upgrade on compatible stands. This optic from manufacturer Kern belongs to the standard achromatic class used for routine inspection, teaching and preparatory viewing before higher-power objectives are engaged. The relatively long working distance eases handling of slides, culture vessels and simple preparations while maintaining the expected field coverage of a 4× achromat. Compact packaging dimensions simplify storage with other nosepiece optics. Select this lens when a 4× / 0,1 achromatic objective with 27 mm working distance is required for educational microscopes, service replacements or everyday laboratory overview imaging.
This article is part of Microscope objectives, eyepieces & optics, in Microscopy & histology.

Questions about Microscope Objective KERN OBB-A3203
What is this article?
Microscope Objective KERN OBB-A3203 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.
