| geometric isomer | <chemistry> Geometric or also called cis-trans isomers are stereoisomers in molecules with restricted rotation about a bond. Cycloalkanes and alkenes form cis-trans isomers due to the restriction of rotation about the double bond or due to the restriction in a ring. In order for an alkene to freely rotate, the pi bond must be broken. This process has a high activation energy and does not occur at room temperature. Cis isomers have the two substituents on each of the carbons of the double bond on the same side, whereas in the trans isomer they are on opposite sides. The expression cis and trans only applies to alkenes or cycloalkanes if one of the substituents on each of the carbons are the same. If there are three or four different substituents, E,Z or R,S nomenclature must be used. (09 Jan 1998) |

| geometric isomerism | A form of isomerism displayed by unsaturated or ring compounds where free rotation about a bond (usually a carbon-carbon bond) is restricted; e.g., the isomerism of a cis-or trans-compound as in oleic acid and elaidic acid. Compare: cis-, entgegen, trans-, zusammen. (05 Mar 2000) |
| geometric mean | The mean calculated as the antilogarithm of the arithmetic mean of the logarithms of the individual values; it can also be calculated as the nth root of the product of n values. (05 Mar 2000) |
| geometric mean diameter | A measure of the central tendency of particle size composition of substrate materials sometimes used as an index of the quality of spawning gravels. Also referred to as D50 size. (09 Oct 1997) |
| 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) |
