| illumination, critical | <microscopy> The formation of an image of the light source in the object field. The Nelsonian method in which the light source is imaged in the plane of the specimen. A ribbon filament or arc lamp is required to give uniform illumination, the lamp must be focusable, the filament position must be adjustable in all directions. The use of an achromatic condenser is advised. Synonym: Nelson illumination. (13 Jan 1998) |

| annular illumination | <microscopy> The result of placing a stop in the first focal plane of the condenser to produce an illuminating cone of light with all the light flux near the surface of the cone. The central part of the cone will be dark. This arrangement is often used for a darkfield effect in low-power work by transmitted light. The condenser must be correctly focused and centreed. By reflected light, darkfield illumination is attained with an annular con-denser fitted around the objective for opaque objects. Annular illumination implies that the object is lighted from all sides. (05 Aug 1998) |
| bright field illumination | <microscopy> The method of lighting the specimen with a solid cone of rays. Transmitted bright field illumination is performed by a substage condenser. Reflected bright field illumination is performed by a vertical illuminator. Compare: dark field illumination (05 Aug 1998) |
| vertical illumination | <microscopy> Bright field illumination by light from the objective which is reflected or scattered from the (usually opaque) object. Illumination is by means of a vertical illuminator placed above the objective. Light is brought into a side tube and directed toward the back aperture of the objective by a tiny mirror or prism, or else by a full-aperture transparent-reflector (thin glass plate) 45[macron] to the axis of the bodytube. (05 Aug 1998) |
| central illumination | axial illumination |
| contact illumination | Illumination of the eye by means of an instrument in contact with the cornea or bulbar conjunctiva. Critical illumination, the precise focusing of the light source directly upon the object being examined. Dark-field illumination, a procedure in which a black circular shield is used to block the majority of the vertically directed rays of light (e.g., the field is dark), and a circumferential, suitably angled, mirrored surface is used to direct the peripheral rays horizontally against the object, thereby reflecting the light vertically through the objective lens and along the optical axis; thus, the object is well illuminated in a contrasting dark background. Synonym: dark-ground illumination. (05 Mar 2000) |
| dark field illumination | <microscopy> Any method of illumination which illuminates the specimen but does not admit light directly to the objective. It may be by substage (dark field) condensers, by stagespot lighting, by special condensers fitted around special objectives for reflected illumination or by the slit ultramicroscope. (05 Aug 1998) |
| dark-ground illumination | dark-field illumination |
| direct illumination | An illumination in which the rays of light are directed downward, almost perpendicularly onto the upper surface of the object, which reflects the rays upward into the optical system. Synonym: erect illumination, vertical illumination. (05 Mar 2000) |
| illumination | 1. The act of illuminating, or supplying with light; the state of being illuminated. 2. Festive decoration of houses or buildings with lights. 3. Adornment of books and manuscripts with coloured illustrations. See Illuminate. 4. That which is illuminated, as a house; also, an ornamented book or manuscript. 5. That which illuminates or gives light; brightness; splendor; especially, intellectual light or knowledge. "The illumination which a bright genius giveth to his work." (Felton) 6. The special communication of knowledge to the mind by God; inspiration. "Hymns and psalms . . . Are framed by meditation beforehand, or by prophetical illumination are inspired." (Hooker) Origin: L. Illuminatio: cf. F. Illumination. Source: Websters Dictionary (01 Mar 1998) |
| illumination, Kohler | <microscopy> A method of microscopical illumination, first described by A. Kohler, in which an image of the source is focused in the lower focal plane of the condenser and the field diaphragm is focused in the specimen plane. (05 Aug 1998) |
| illumination, oblique | <microscopy> Illumination from light inclined at an oblique angle to the optical axis. (05 Aug 1998) |
| oblique illumination | Illumination in which a beam of light is directed diagonally to an object so that it is brilliantly illuminated while the surrounding area is in shadow. Synonym: lateral illumination, oblique illumination. Kohler illumination, a method of illumination of microscopic objects in which the image of the light source is focused on the substage condenser diaphragm and the diaphragm of the light source is focused in the same plane with the object to be observed; maximises both the brightness and uniformity of the illuminated field. (05 Mar 2000) |
| erect illumination | An illumination in which the rays of light are directed downward, almost perpendicularly onto the upper surface of the object, which reflects the rays upward into the optical system. Synonym: erect illumination, vertical illumination. (05 Mar 2000) |
| Koehler illumination | <microscopy> Mode of microscope illumination in which the light source is imaged onto the condenser iris diaphragm and the field diaphragm (in front of the lamp collector lens) is imaged by the condenser onto the plane of focus of the specimen. With Koehler illumination, the aperture and field can be regulated independently to provide maximum resolution and optimum contrast. Also, a field with uniform illumination is obtained, circumscribed by the image of the field diaphragm. (05 Aug 1998) |
