| microscope, compound | A microscope that consists of two microscopes in series, the first serving as the ocular lens (close to the eye) and the second serving as the objective lens (close to the object to be viewed). Credit for creating the compound microscope goes usually to the dutch spectaclemakers hans and zacharias janssen who in 1590 invented an instrument that could be used as either a microscope or telescope. The compound microscope evolved into the dominant type of optical microscope today. (12 Dec 1998) |
|---|---|
| microscope, electron | <microscopy> An electron-optical device which produces a magnified image of an object. Detail may be revealed by virtue of selective transmission, reflection, or emission of electrons by the object. (05 Aug 1998) |
| microscope, field emission | <microscopy> An image-forming device in which a strong electrostatic field causes cold emission of electrons from a sharply rounded point or from a specimen that has been placed on that point. The electrons are accelerated to a phosphorescent screen, or photographic film, giving a visible picture of the variation of emission over the specimen surface. (05 Aug 1998) |
| microscope, fluorescent | A microscope equipped to examine material that fluoresces under ultraviolet (uv) light. (12 Dec 1998) |
| microscope, Greenough | <microscopy> A stereoscopic microscope with paired objectives, prisms, and eyepieces invented by H. Greenough. The name is sometimes incorrectly used for any stereoscopic microscope with paired objectives showing erect images. (05 Aug 1998) |
| microscope mirror | <microscopy> Usually plane on one side and concave on the other. The flat side is generally used unless the objective is of very low power and there is no condenser. The mirror should be so mounted that the concave side can be focused on the specimen. (05 Aug 1998) |
| microscope, simple | <microscopy> A microscope that has a single converging lens (or a combination of lenses that function optically as a single converging lens). Anton van leeuwenhoek (1632-1723) made good use of the simple microscope to look at the life within a drop of water, and such. The magnifying properties of lenses had been well known in ancient times (for example to the greeks and romans) but it was not until about 1600 that it became possible to make small lenses with the precision needed to make a microscope. (12 Dec 1998) |
| microscope, stereoscopic | <microscopy> Either one of two kinds: binocular-bi-nobjective, such as the Greenough microscope type, and binocular microscope with common main objective. See: stereomicroscope. (05 Aug 1998) |
| microscope, X-ray | <microscopy> A device for producing enlarged images of a specimen by means of X rays. Dioptric systems, analogous to light microscopes, are not available, but contact microradiography, point-projection, and reflection techniques (which see) provide practical alternatives. (05 Aug 1998) |
| monobjective binocular microscope | <instrument, microscopy> A microscope with one objective and two bodies, for binocular vision, not necessarily stereoscopic. (05 Aug 1998) |
| monocular microscope | <instrument, microscopy> A microscope with one objective and one bodytube for monocular vision. (05 Aug 1998) |
| colour-contrast microscope | <instrument> A type of microscope in which the condenser stop is of one colour and the annulus is a complement of it so that unstained objects are observed in one colour on a field of the other. (05 Mar 2000) |
| comparator microscope | <instrument> A device constructed with one or more microscope's having micrometer eyepieces used to measure dimensional changes during setting or temperature changes. (05 Mar 2000) |
| compound microscope | <instrument> A microscope (an optical instrument that augments the power of the eye to see small objects) which consists of two microscopes in series, the first serving as the ocular lens (close to the eye) and the second serving as the objective lens (close to the object to be viewed). Credit for creating the compound microscope goes usually to the Dutch spectaclemakers Hans and Zacharias Janssen who in 1590 invented an instrument that could be used as either a microscope or telescope. The compound microscope has evolved into the dominant type of optical microscope today. (12 Dec 1998) |
| confocal microscope | <instrument> A microscope that allows the observer to visualise objects in a single plane of focus, thereby creating a sharper image (usually the objects are fluorescent molecules); a refinement of this microscope uses optical sectioning and a computer to record serial sections. This permits three-dimensional reconstruction. (05 Mar 2000) |
