| 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 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) |
| achromatic objective | <microscopy> An objective that is corrected chromatic for two colours, and spherically for one, usually in the yellow-green part of the spectrum. (05 Aug 1998) |
| apochromatic objective | <microscopy> A lens system whose secondary chromatic aberrations have been substantially reduced. It is designed to provide the same focal length for three wavelengths and freedom from spherical aberration for two wavelengths of light. The magnification can still vary with wavelength in which case a compensating eyepieces used to cancel the coloured fringes. (05 Aug 1998) |
| plan apochromatic objective lens | <physics> A modern, high-numerical aperture microscope objective lens designed with high degrees of corrections for various aberrations. It is corrected for spherical aberration in four wavelengths (dark blue, blue, green, and red), for chromatic aberration in more than these four wavelengths, and for flatness of field. A single Plan Apo objective may contain as many as 11 lens elements. (05 Aug 1998) |
| homogeneous immersion objective | <microscopy> An objective to be immersed in a liquid of a certain refractive index and dispersion value as specified by the manufacturer of the objective. An oil-immersion objective, the most important type, is intended to be immersed in cedarwood oil (nD = 1.515) or in its manmade optical equivalent. A water-immersion objective is for dipping into an aqueous specimen mount. Alpha-monobromonaphthalene has such a high refractive index (nD = 1.66) that a very highly resolving objective (1.60 numerical aperture) was designed to be immersed in that liquid, for use by reflected light on metals and other opaque objects. (05 Aug 1998) |
| semi-apochromatic objective | <microscopy> A compromise, in the correction for chromatic and spherical aberration, between achromatic and apochromatic objectives, such as a fluorite objective. (05 Aug 1998) |
| dark field objective | <microscopy> Certain objectives for high-power, dark fieldwork equipped with iris diaphragms or funnel stops so that their apertures may be reduced to correspond to the dark field con-denser with which they are used. (05 Aug 1998) |
| dry objective | <microscopy> Any microscope objective designed for use without immersion liquids. (05 Aug 1998) |
| immersion objective | <microscopy> An objective in which the medium of high refractive index and is used in the object space to increase the numerical aperture and hence the resolving power of the lens. See: homogeneous immersion of objective. (05 Aug 1998) |
| objective | 1. <psychology> Perceptible to the external senses. 2. <ophthalmology> The lens or system of lenses in a microscope (or telescope) that is nearest to the object under examination. Origin: L. Objectivus (18 Nov 1997) |
| objective assessment data | Those facts presented by the client that show his/her perception, understanding and interpretation of what is happening. (05 Mar 2000) |
