| 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. |

| 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 | <optics> Of or pertaining to a thread or line; characterised by threads stretched across the field of view; as, a filar microscope; a filar micrometer. Origin: L. Filum a thread. Source: Websters Dictionary (01 Mar 1998) |

| filar mass | A filamentous plasmatic material, beaded with granules, demonstrable by means of vital staining in the immature red blood cells. Synonym: alpha substance, filar mass, filar substance, substantia reticularis, substantia reticulofilamentosa. Synonym: reticular formation. (05 Mar 2000) |
| filar micrometre | <microscopy> An eyepiece equipped with a fiducial line in its focal plane that is movable by means of a calibrated micrometre screw in order to make accurate measurements of length. Synonym: filar eyepiece. (05 Aug 1998) |
| filar micrometre ocular | <microscopy> A micrometre ocular with crossed lines which can be simultaneously focused in and moved across the field by means of a micrometre screw. The amount of displacement can be read in 0.01 steps on the micrometre drum head. This makes a very delicate measuring device, since calibration of the micrometre scale by means of a stage micrometre gives values for each interval on the drum head which are much less than the resolving power of the highest-aperture objectives.

| filar substance | A filamentous plasmatic material, beaded with granules, demonstrable by means of vital staining in the immature red blood cells. Synonym: alpha substance, filar mass, filar substance, substantia reticularis, substantia reticulofilamentosa. Synonym: reticular formation. (05 Mar 2000) |
