| 설명 | 현미경을 통해서 볼수 있는 대상물을 측정하는 기구. 정확한 피치를 가진 나사를 이용하여 길이를 잰다. U자형 프레임의 한쪽 끝에는 고정된 앤빌(anvil)이 있고, 다른쪽 끝의 슬리브(sleeve) 안쪽은 암나사로 되었으며, 정밀도가 높은 피치의 작은 수나사인 스핀들이 그 속에 들어있다. 스핀들의 바깥쪽에는 심블(thimble)이 있으며, 이것을 회전시키면 스핀들이 축방향으로 이동하게 되어 있다. 슬리브에는 축방향으로 눈금이 매겨졌고, 심블에는 원주 방향으로 원주를 50등분한 눈금이 매겨져 있어 1눈금으로 0.01mm를 읽을 수 있다. |

| 영문 | microscope | 한글 | 현미경 |
|---|---|---|---|
| 설명 | 물체의 미세한 부분을 확대하여 관찰하는 장치. 대개의 경우는 대물렌즈와 접안렌즈를 갖추고 있는 현미경을 말하나, 넓은 뜻으로는 전자선을 이용하는 전자현미경을 포함하며, 확대경도 단일 렌즈계를 갖는 단현미경이라 할 수 있다. 종류와 형은 사용목적-제작연대-제작 회사의 차이에 따라 여러 가지가 있으나 구조적으로 분류하면, 가장 일반적인 투과현미경 이외에 금속현미경-편광현미경-형광현미경-위상차현미경-자외선현미경 등의 특수한 것들이 있다. 현미경이 물체의 상을 확대하는 원리는 초점거리가 짧은 대물렌즈에 의하여 얻어지는 확대된 도립실상을 접안렌즈로 다시 확대하는 것이다. 이 결상관계는 대단히 예민하여 물체와 대물렌즈 사이의 거리가 조금만 변하여도 바른 상을 맺지 못한다. |

| micrometer | An instrument, used with a telescope or microscope, for measuring minute distances, or the apparent diameters of objects which subtend minute angles. The measurement given directly is that of the image of the object formed at the focus of the object glass. Circular, or Ring, micrometer, a metallic ring fixed in the focus of the object glass of a telescope, and used to determine differences of right ascension and declination between stars by observations of the times at which the stars cross the inner or outer periphery of the ring. Double image micrometer, a micrometer in which two images of an object are formed in the field, usually by the two halves of a bisected lens which are movable along their line of section by a screw, and distances are determined by the number of screw revolutions necessary to bring the points to be measured into optical coincidence. When the two images are formed by a bisected objects glass, it is called a divided-object-glass micrometer, and when the instrument is large and equatorially mounted, it is known as a heliometer. Double refraction micrometer, a species of double image micrometer, in which the two images are formed by the double refraction of rock crystal. Filar, or Bifilar, micrometer. See Bifilar. <mechanics> Micrometer caliper or gauge, a caliper or gauge with a micrometer screw, for measuring dimensions with great accuracy. Micrometer head, the head of a micrometer screw. Micrometer microscope, a compound microscope combined with a filar micrometer, used chiefly for reading and subdividing the divisions of large astronomical and geodetical instruments. Micrometer screw, a screw with a graduated head used in some forms of micrometers. Position micrometer. See Position. Scale, or Linear, micrometer, a minute and very delicately graduated scale of equal parts used in the field of a telescope or microscope, for measuring distances by direct comparison.

| slide micrometer | A scale made on a microscope slide with lines ruled in divisions, usually, of 0.01 mm; typically used to calibrate an ocular micrometer. (05 Mar 2000) |
| ocular micrometer | A glass disk that fits in a microscope eyepiece and that has a ruled scale; when calibrated with a slide micrometer, direct measurements of a microscopic object can be made. (05 Mar 2000) |
| filar micrometer | An ocular micrometer with a line moved by a ruled drum such that a movement of the line of 5 um or less may be made in relation to fixed parallel lines. (05 Mar 2000) |
| binocular microscope | <instrument, microscopy> A microscope fitted with double eyepieces for vision with both eyes. The purpose in dividing the same image from a single objective of the usual compound micro-scope is to reduce eyestrain and muscular fatigue which may result from monocular, high-power microscopy. The purpose in obtaining a different image for each of two oculars is to provide stereoscopy by means of two different angles of view. There are two kinds of stereoscopic microscopes: binobjective (Greenough) older type and monobjective (common main objective) newer type. (See stereo microscope, Greenough microscope, etc.) (05 Aug 1998) |
| Rheinberg microscope | <instrument> A modified form of dark-field microscope in which the central opaque stop in the condenser is replaced by a coloured filter, producing a background of contrasting colour against which the specimen is illuminated. (05 Mar 2000) |
| Greenough microscope | <instrument, microscopy> One of two kinds of stereomicroscopes with two separate compound microscopes, one for each eye, focused on the same object. The other kind has a common main objective. See: binocular microscope. (05 Aug 1998) |
| phase-contrast microscope | <instrument> A specially constructed microscope that has a special condenser and objective containing a phase-shifting ring whereby small differences in index of refraction are made visible as intensity or contrast differences in the image; particularly useful for examining structural details in transparent specimens such as living or unstained cells and tissues. (05 Mar 2000) |
| microscope | <instrument> A piece of laboratory equipment that is used to magnify small things that are too small to be seen by the naked eye, or too small for the details to be seen by the naked eye, so that their finer details can be seen and studied. Examples are the light (or optical) microscope, electron microscope, X-ray microscope, and acoustic microscope. (09 Oct 1997) |
| 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) |
