| rectified optics | <microscopy> Microscope lens system correcting the rotation of polarized light that takes place at high-incidence-angle interfaces between the polarizer and analyser. Rectification provides high extinction for polarized-light and Differential Interference Contrast microscopy at high numerical apertures, thus permitting bifringence or phase retardation combined with high in g low phase. (05 Aug 1998) |
| confocal optics | <microscopy> A (microscope) optical system in which the condenser and objective lenses both focus onto one single point in the specimen. Generally, the image of a pinhole source is focused onto a point in the specimen, and that point is focused by the objective lens onto a point detector or through a mask with a pinhole aperture. With confocal optics, the Abbe limit of resolution can be exceeded since only a limited region of the specimen is viewed at any onetime. (05 Aug 1998) |
| optics | That branch of physical science which treats of the nature and properties of light, the laws of its modification by opaque and transparent bodies, and the phenomena of vision. Origin: Cf. F. Optique, L. Optice, Gr. (sc). See Optic. Source: Websters Dictionary (01 Mar 1998) |
| electron optics | <study> The science that deals with propagation electrons, as light optics deals with that of light and its phenomena. Eye lens (see lens, eye). (05 Aug 1998) |
| antibiotic eye drops | <pharmacology> A medication that is pH balanced to allow placement into the eye for the purpose of killing bacteria. Examples include: Bleph-10, Chloromycetin, Cortisporin-Ophthalmic, Gantrisin, Genoptic, Gentacidin, Garamycin, Gantrisin, Ilotycin, Sodium Sulamyd and Sulphair. (27 Sep 1997) |
| burning drops sign | <clinical sign> In certain cases of perforated gastric ulcer, a sensation as of drops of hot liquid falling into the abdominal cavity or as of a stream of intensely hot liquid being poured into the cavity. (05 Mar 2000) |
| stomach drops | A stomachic tonic, usually tincture of gentian, alone or with other stomachics. (05 Mar 2000) |
| nose drops | A liquid preparation intended for intranasal administration with a medicine dropper. Most frequently used for decongestion of the nasal passages but can be used for any other appropriate indication. (05 Mar 2000) |
| drops | A popular term for a medicine taken in doses measured by drops's, usually a tincture, or applied by dropping, as an eyewash. (05 Mar 2000) |
| eye drops | See: eyewash, ophthalmic solutions. (05 Mar 2000) |
| knock-out drops | A popular name for chloral alcoholate given with criminal intent to produce unconsciousness rapidly; it is formed by adding chloral hydrate to beer or some stronger alcoholic liquor. (05 Mar 2000) |
