| 설명 | 미립자를 관찰할 수 있는 특수 현미경. 특수 조명법에 의해서 보통현미경으로는 볼 수 없는 미립자를 분별할 수 있는 현미경이다. 암시야현미경이라고도 한다. 1903년 독일의 R.지그몬디에 의해 만들어졌으며, 그는 이것을 사용하여 콜로이드의 연구에 공적을 남겼다. 어두운 방에 빛이 들면 먼지가 빛나 보이는 틴들현상을 이용한 것으로서 카르디오이드 집광기나 파라볼로이드 집광기라고 하는 특수한 모양의 집광기를 사용해서 시료를 옆에서 비추어 그것에 의한 산란광을 관측한다. 접안경을 들여다보면 암측의 배경 속에 미립자가 별과 같이 빛나 보인다. 현재 사용되는 것은 0.25~0.04μm의 미립자까지 확인할 수 있다. |

| ultramarine | <chemistry> A blue pigment formerly obtained by powdering lapis lazuli, but now produced in large quantities by fusing together silica, alumina, soda, and sulphur, thus forming a glass, coloured blue by the sodium polysulphides made in the fusion. Also used adjectively. Green ultramarine, a green pigment obtained as a first product in the manufacture of ultramarine, into which it is changed by subsequent treatment. Ultramarine ash or ashes, a pigment which is the residuum of lapis lazuli after the ultramarine has been extracted. It was used by the old masters as a middle or neutral tint for flesh, skies, and draperies, being of a purer and tenderer gray that produced by the mixture of more positive colours. Fairholt. Origin: Cf. Sp. Ultramarino. So called because the lapis lazuli was originally brought from beyond the sea, from Asia. Source: Websters Dictionary (01 Mar 1998) |

| ultramicroscope | <instrument, microscopy> A term applied to particles less than 0.1 ~m in diameter, hence too small to be truly resolved by the light micro- scope. Under the ultramicroscope they look like stars in the sky. Their differences in size are merely indicated by differences in brightness. (05 Aug 1998) |
| ultramicroscopic | <optics> Particles which, although visible in the ultramicroscope, are too small to be resolved by visible light. This places their size between 0.2 Lm and 0.005 Lm. (05 Aug 1998) |
| ultramicrotome | A microtome used in cutting sections 0.1 um thick, or less, for electron microscopy. (05 Mar 2000) |
| ultramicrotomy | The cutting of ultrathin sections for electron microscopy by use of an ultramicrotome. (05 Mar 2000) |
| ultramontanism | The principles of those within the Roman Catholic Church who maintain extreme views favoring the pope's supremacy; so used by those living north of the Alps in reference to the Italians; rarely used in an opposite sense, as referring to the views of those living north of the Alps and opposed to the papal claims. Cf. Gallicanism. Origin: Cf. F. Ultramontanisme. Source: Websters Dictionary (01 Mar 1998) |

| ultramicroscope |
The ultramicroscope is a system of illumination for extremely small objects such as colloidal particles, fog droplets, or smoke particles. The objects are held in liquid or gaseous suspension in an enclosure with an intensely black background (usually a black body) and illuminated with a convergent pencil of very bright light entering from one side and coming to focus in the field of view - the "Tyndall cone" familiar in experiements on scattering. ...

| ultramicrotome |
A microtome is a mechanical instrument used to cut very thin slices for microscopic examination. Most microtomes use a steel blade and are used to prepare sections of animal, plant or human tissues for histology. The most common applications of microtomes are: * Traditional histological technique: tissues are hardened by replacing water with paraffin. Sections are stained and examined with a visible light microscope. Sections are 2 to 10 micrometres thick. ...
