| 설명 | 눈속의 장기중 하나에 해당. 각막을 통과한 빛은 수정체를 통과하여 망막에 상이 맺히게 되고, 망막은 이 들어온 빛을 자극을 신경세포가 알 수 있는 신호체계로 바꾸어 뇌에 전달해 주게 된다. 각막과 수정체의 중요한 역할은 굴절력을 증가시키는 것이다. 그리하여 올바로 상이 망막에 맺힐 수 있도록 도와주게 된다.  |

| immersion of a lens | <physics> With nearly all high-power lenses, it is intended that the spaces between the condenser and the slide, and the specimen and the front lens of the objective be filled with an immersion liquid. Owing to the limitations imposed by the critical-angle phenomenon, numerical apertures are impossible exceeding 1.0 without immersion. In addition, immersion makes possible the use of the naturally aplanatic points of the front lens element of the objective. (05 Aug 1998) |

| immersion lens | An objective (for a microscope) constructed in such a manner that the lower lens may be moved downward into direct contact with a fluid which is placed on the object being examined; by using a fluid with a refractive index closely similar to that of glass, the loss of light is minimised. (05 Mar 2000) |

| homogeneous immersion | In immersion microscopy, use of a fluid, such as oil, that has a refractive index virtually identical to that of glass, providing the highest possible numerical aperture. (05 Mar 2000) |
| 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) |
| immersion | 1. The act of immersing, or the state of being immersed; a sinking within a fluid; a dipping; as, the immersion of Achilles in the Styx. 2. Submersion in water for the purpose of Christian baptism, as, practiced by the Baptists. 3. The state of being overhelmed or deeply absorbed; deep engagedness. "Too deep an immersion in the affairs of life." (Atterbury) 4. <astronomy> The dissapearance of a celestail body, by passing either behind another, as in the occultation of a star, or into its shadow, as in the eclipse of a satellite; opposed to emersion. Immersion lens, a microscopic objective of short focal distance designed to work with a drop of liquid, as oil, between the front lens and the slide, so that this lens is practically immersed.

| immersion bath | A therapeutic bath in which the whole person or a body part is totally immersed in the therapeutic substance. (05 Mar 2000) |
| immersion foot | A condition of the feet produced by prolonged exposure of the feet to water. Exposure for 48 hours or more to warm water causes tropical immersion foot or warm-water immersion foot common in vietnam where troops were exposed to prolonged or repeated wading in paddy fields or streams. Trench foot results from prolonged exposure to cold, without actual freezing. It was common in trench warfare during world war I, when soldiers stood, sometimes for hours, in trenches with a few inches of cold water in them. (andrews' diseases of the skin, 8th ed, p27) (12 Dec 1998) |
| immersion liquid | <microscopy> Any liquid occupying the space between the object and microscope objective. Such a liquid is usually required by objectives of 3-mm focal length or less. For best results (i.e., resolution) the liquid should be used between the condenser and the microscope slide. Immersion objectives for transmitted light are designed for use with either oil, glycerin, or water, the refractive index of the liquid and the coverslip (if any) being the determining factor. The liquid and the front lens of the objective should ideally coincide in index and in dispersion value. See: homogeneous immersion objective (05 Aug 1998) |
| immersion medium | <microscopy> In microscopy the medium used to immerse the specimen, the space between the objective lens and coverslip, or the condenser lens front element and the slide. For the latter purposes, cedar or synthetic oils with refractive indices and dispersions approximating the front elements of the lens are used for homogeneous immersion. Homogeneous immersion provides high numerical aperture, less light loss and depolarisation, and generally improved correction of aberrations. Glycerol or water may be used for immersion of particular lenses, but for high-numerical aperture lenses designed to be used with a variety of immersion media, proper adjustment of the correction collars is necessary, the refractive index, thickness, and dispersion of the immersion media and coverslips all enter into the corrections for aberrations of high-numerical aperture objective and condenser lenses. (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) |
| achromatic lens | A compound lens made of two or more lens's having different indices of refraction, so correlated as to minimise chromatic aberration. (05 Mar 2000) |
| acoustic lens | In ultrasonography, a lens used to focus or diverge a sound beam; may be simulated by electronic manipulation of signals. (05 Mar 2000) |
| anterior pole of lens | The central point on the anterior surface of the lens of the eye. Synonym: polus anterior lentis. (05 Mar 2000) |
| anterior surface of lens | The anterior surface of the lens of the eye. Synonym: facies anterior lentis. (05 Mar 2000) |
| aplanatic lens | A lens designed to correct spherical aberration and coma (q.v.). Synonym: periscopic meniscus. (05 Mar 2000) |
| apochromatic lens | A compound lens designed to correct both spherical and chromatic aberrations. (05 Mar 2000) |
