Two Leica oil immersion microscope objective lenses; left 100×, right 40×. The objective lens of a microscope is the one at the bottom near the sample. At its simplest, it is a very high-powered magnifying glass, with very short focal length. This is brought very close to the specimen being examined so that the light from the specimen comes ...
A Wild M400 macroscope. A macroscope or photomacroscope in its camera-equipped version (in German: makroskop / photomakroskop) is a type of optical microscope developed and named by Swiss microscope manufacturers Wild Heerbrugg and later, after that company's merger with Leica in 1987, by Leica Microsystems of Germany, optimised for high quality macro photography and/or viewing using a single ...
Original - Two Leica oil immersion microscope objective lenses; left 100x, right 40x. This is a high quality image of an object, a microscope objective lens, most people would otherwise not get a chance to see.

The Royal Microscopical Society (RMS) thread, also known as society thread, is a special 0.8" diameter x 36 tpi Whitworth thread used for microscope objective lenses and Leitz was a major manufacturer of microscopes, so the tooling at the plant was already set up to produce the Whitworth thread form.
Objective stop dispersion staining takes advantage of the fact that all light unaltered by the presence of particles in the field of view is focused at the back focal plane of the objective. If the substage condenser iris is closed down then all of the direct light is focused into a small image of the opening in the substage condenser iris at ...
Leica Microsystems GmbH is a German microscope manufacturing company. It is a manufacturer of optical microscopes , equipment for the preparation of microscopic specimens and related products. There are ten plants in eight countries with distribution partners in over 100 countries.
Between approximately 1976 and 1993, the manufacturers Wild Heerbrugg (Switzerland) and subsequently, Leica Microsystems offered a dedicated microscopy system for macro photography, the macroscope line, with improved optical performance for photography at the expense of the stereo imaging facility of the stereo microscope; this system came with ...
The area provides a reference unit, for example in reference ranges for urine tests. [3]Used for grading of soft tissue tumors: Grading, usually on a scale of I to III, is based on the degree of differentiation, the average number of mitoses per high-power field, cellularity, pleomorphism, and an estimate of the extent of necrosis (presumably a reflection of rate of growth).
