Optical microscopy is used for medical diagnosis, the field being termed histopathology when dealing with tissues, or in smear tests on free cells or tissue fragments. [citation needed] In industrial use, binocular microscopes are common.
The eye relief of an optical instrument (such as a telescope, a microscope, or binoculars) is the distance from the last surface of an eyepiece within which the user's eye can obtain the full viewing angle. If a viewer's eye is outside this distance, a reduced field of view will be obtained.
Binoculars or field glasses are two refracting telescopes mounted side-by-side and aligned to point in the same direction, allowing the viewer to use both eyes (binocular vision) when viewing distant objects. Most binoculars are sized to be held using both hands, although sizes vary widely from opera glasses to large pedestal-mounted military ...
1846: Carl Zeiss founded Carl Zeiss AG, to mass-produce microscopes and other optical instruments. 1850s: John Leonard Riddell, Professor of Chemistry at Tulane University, invents the first practical binocular microscope. [13] 1863: Henry Clifton Sorby develops a metallurgical microscope to observe structure of meteorites.
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 ...
Several objective lenses on a microscope. Objective lenses of binoculars. In optical engineering, an objective is an optical element that gathers light from an object being observed and focuses the light rays from it to produce a real image of the object.
