|---|---|---|---|
| 설명 | 1. 한쪽 눈에 빛을 비추면, 이 빛은 시각신경에 의해 뇌에 전달되고, 이 자극은 사람의 의지와 무관하게 곧, 눈돌림신경으로 전달되어 양쪽 눈의 동공이 축소하게 된다. 이런 모든 일련의 과정을 빛반사라 부르는데 이것은 사람이 어두운 곳에 가거나 어두운 곳에서 갑자기 밝은 곳에 나갔을 때, 동공이 반사적으로 움직이는 것과 같은 것이다. 2. 고막에서 반사하는 광상. 3. 망막경의 거울로 망막에서 반사하는 고리모양의 많은 점. |

| 영문 | ultraviolet | 한글 | 자외선 |
|---|---|---|---|
| 설명 | 보라색보다 더욱 파장이 짧은 400nm 이하의 볼 수 없는 광선이며 다음의 3종으로 나눈다. ① 200~290nm(UVC): 저압램프에서 조사되는 것으로 DNA를 저해하며 피부에 조사되면 홍반이 생긴다. 대기중의 O3나 H2O에서 흡수된다. ② 290~320nm(UVB): 피부가 햇볕에 타서 검게 되며 지나치면 수포나 피부암을 일으킬 위험이 있다. ③ 320~400nm(UVA): 지표면에 많으며 무해하다. 다량이 폭로되면 피부에 색소침착을 일으킨다. |

|---|---|---|---|
| 설명 | 290~320nm의 자외선. 일광화상과 그을림을 가장 효과적으로 유발한다. 백인에서 자외선 과다는 피부암을 유발할 수 있다. |

| 영문 | ultraviolet C | 한글 | 짧은파장자외선 |
|---|---|---|---|
| 설명 | 200~290nm의 자외선 방사. UVC라고도 한다. 일광의 UVC는 지구 표면에 도달하지 않는다. 멸균/수은아크등은 일광화상과 각막염을 유발할 수 있다. |

| vital ultraviolet | Rays necessary or helpful to normal growth; they promote calcium metabolism, are antirachitic in action, and have wavelengths between 3200 and 2900 A |

| microscopy, ultraviolet | Microscopy in which the image is formed by ultraviolet radiation and is displayed and recorded by means of photographic film. (12 Dec 1998) |
| spectrophotometry, ultraviolet | Determination of the spectra of ultraviolet absorption by specific molecules in gases or liquids, for example cl2, so2, no2, cs2, ozone, mercury vapor, and various unsaturated compounds. (12 Dec 1998) |
| intravital ultraviolet | Having wavelengths of 3900 to 3200 A |
| extravital ultraviolet | Having wavelengths of 2900 to 1850 A |
| ultraviolet | <physics> Continuous spectrum beyond the violet end of the visible spectrum (wavelength less than 400nm) and above the X-ray wavelengths (greater than 5 nm). Glass absorbs UV, so optical systems at these wavelengths have to be of quartz. Nucleic acids absorb UV most strongly at around 260nm and this is the wavelength most likely to cause mutational damage (by the formation of thymine dimers). It is the UV component of sunlight that causes actinic keratoses to form in skin, but that is also required for Vitamin D synthesis. (18 Nov 1997) |
| ultraviolet A | Ultraviolet radiation from 320 to 400 nm that causes skin tanning but is very weakly sunburn-producing and carcinogenic. (05 Mar 2000) |
| ultraviolet B | Ultraviolet radiation from 290 to 320 nm that most effectively causes sunburning and tanning; excessive UVB exposure is a cause of cancer of fair skin. (05 Mar 2000) |
| ultraviolet C | Ultraviolet radiation from 200 to 290 nm; UVC in sunlight does not reach the surface of the earth; germicidal and mercury arc lamps may cause sunburn and photokeratitis. (05 Mar 2000) |
| ultraviolet keratoconjunctivitis | Acute keratoconjunctivitis resulting from exposure to intense ultraviolet irradiation. Synonym: actinic conjunctivitis, arc-flash conjunctivitis, flash keratoconjunctivitis, ophthalmia nivalis, snow conjunctivitis, welder's conjunctivitis. (05 Mar 2000) |
| ultraviolet lamp | A lamp that emits rays in the ultraviolet band of the spectrum. See: ultraviolet. (05 Mar 2000) |
| ultraviolet microscope | <instrument> A microscope having optics of quartz and fluorite that allow transmission of light waves shorter than those of the visible spectrum, i.e., below 400 nm; the image is made visible by photography, fluorescence of special glasses, or television; in a scanning instrument the receptor is a multiplier phototube. (05 Mar 2000) |
| ultraviolet radiation | <physics> Invisible light, next to visible light in the electromagnetic spectrum. The most common source of ultraviolet radiation is the sun. Acronym: UV (16 Dec 1997) |
| ultraviolet rays | That portion of the electromagnetic spectrum immediately below the visible range and extending into the X-ray frequencies. The longer wavelengths (near-uv or biotic or vital rays) are necessary for the endogenous synthesis of vitamin d and are also called antirachitic rays; the shorter, ionizing wavelengths (far-uv or abiotic or extravital rays) are viricidal, bactericidal, mutagenic, and carcinogenic and are used as disinfectants. (12 Dec 1998) |
| ultraviolet spectrum | The electromagnetic spectrum beyond the violet end of the visible spectrum. (05 Mar 2000) |
| ultraviolet light | radiation lying in the ultraviolet range |
