Schematic optical diagram of the Bausch & Lomb Spectronic 20 Colorimeter. As shown in the schematic optical diagram (see left), polychromatic light from a source in the system passes through lenses which are reflected and dispersed by the diffraction grating to restrict the range of light wavelengths. This restricted range of wavelengths is ...
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.
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 ...
John Jacob Bausch (born Johann Jakob Bausch; July 25, 1830 – February 14, 1926) was a German-American maker of optical instruments who co-founded Bausch & Lomb (with Henry Lomb). Over six decades he transformed his small, local optical shop into a large-scale international enterprise, pioneering the American optical industry.
[6] Bausch + Lomb was a public company listed on the NYSE, until it was acquired by private equity firm Warburg Pincus in 2007. In May 2013, Canadian-based Valeant Pharmaceuticals announced that it would acquire Bausch + Lomb from Warburg Pincus for $4.5 billion in cash. [7] [8] The deal, which was approved by shareholders, closed on August 5 ...
The optical microscope, also referred to as a light microscope, is a type of microscope that commonly uses visible light and a system of lenses to generate magnified images of small objects. Optical microscopes are the oldest design of microscope and were possibly invented in their present compound form in the 17th century.
The stereo, stereoscopic or dissecting microscope is an optical microscope variant designed for low magnification observation of a sample, typically using light reflected from the surface of an object rather than transmitted through it. The instrument uses two separate optical paths with two objectives and eyepieces to provide slightly ...
Diagram illustrating the light path through a dark-field microscope. The steps are illustrated in the figure where an inverted microscope is used. Light enters the microscope for illumination of the sample. A specially sized disc, the patch stop (see figure), blocks some light from the light source, leaving an outer ring of illumination. A wide ...
