| Maddox, Ernest | <person> English ophthalmologist, 1860-1933. See: Maddox's rod. (05 Mar 2000) |
|---|---|
| Maddox's rod | A glass rod, or a series of parallel glass rod's, that converts the image of a light source into a streak of light perpendicular to the axis of the rod. The position of this streak in relation to the image of the light source seen by the fellow eye indicates the presence and amount of heterophoria. (05 Mar 2000) |
| refracting angle of a prism | The angle between two plane surfaces of a prism. Synonym: refracting angle of a prism. (05 Mar 2000) |
| Risley's rotary prism | A prism with a circular base that is rotated in a metal frame marked with a scale; used in examination of ocular muscle imbalance. (05 Mar 2000) |
| prism | <microscopy> A transparent body with at least two polished plane faces inclined with respect to each other, from which light is reflected or through which light is refracted. When light is refracted by a prism whose refractive index exceeds that of the surrounding medium, it is deviated or bent toward the thicker part of the prism. (05 Aug 1998) |
| prism bar | A graduated series of prism bar's mounted on a frame and used in ocular diagnosis. (05 Mar 2000) |
| prism cover test | Measurement of the deviation in strabismus by the alternate cover test combined with neutralization for the deviation using prisms. (05 Mar 2000) |
| prism diopter | The unit of measurement of the deviation of light in passing through a prism, being a deflection of 1 cm at a distance of 1 m. (05 Mar 2000) |
| prism illuminator | <microscopy> A 45 to ~0-degree prism interposed in the tube of a light microscope for the purpose of directing an intense beam of light through the objective onto the object. The prism illuminator utilises about one half the aperture of the objective as does the mirror illuminator with an attending loss of resolution over that obtainable with either a plane glass illuminator or a pellicle mirror. See: metallography, Nicol prism. (05 Aug 1998) |
| prism vergence test | Measurement of the amplitude of fusion by placing prisms of gradually increasing power in the direction tested until diplopia occurs. (05 Mar 2000) |
| Nicol prism | <physics> A prism, used for polarizing or analysing light, made by cementing together, with Canada balsam, two pieces of calcite in such a way that the extraordinary ray from the first piece passes through the second piece while the ordinary ray is reflected to the side into an absorbing layer of black paint. When two Nicol prisms are crossed, therefore, no light passes through. A polarizing prism made of two pieces of calcite specially cut, ground, polished and cemented. A transmitted beam splits into two polarized components, one of which is refracted into and absorbed by the asphalt mount. The remaining polarized beam is transmitted. Modifications of this prism are common. The Nicol prism (nicol) has generally been superseded by a polarizing film such as Polaroid. See: polars, polarizer, analyser. (05 Aug 1998) |
| tidal prism | The change in the volume of water covering an area, such as a wetland, between a low tide and the subsequent high tide. (09 Oct 1997) |
| Fresnel prism | A prism composed of concentric annular rings. (05 Mar 2000) |
| Auer rods | Rod-shaped structures of uncertain nature in the cytoplasm of immature myeloid cells, especially myeloblasts, in acute myelocytic leukaemia; may be an abnormal form of lysosomes; they contain peroxidase and acid phosphatase, and stain red by azure-eosin stains. Synonym: Auer rods. (05 Mar 2000) |
| gram-negative aerobic rods and cocci | <microbiology> A group of gram-negative bacteria consisting of rod- and coccus-shaped cells. They are both aerobic (able to grow under an air atmosphere) and microaerophilic (grow better in low concentrations of oxygen) under nitrogen-fixing conditions but, when supplied with a source of fixed nitrogen, they grow as aerobes. (12 Dec 1998) |
