| polarimeter | <optics> An instrument for determining the amount of polarization of light, or the proportion of polarized light, in a partially polarized ray. Origin: Polar. Source: Websters Dictionary (01 Mar 1998) |
| polarimetry | <optics> The art or process of measuring the polarization of light. Source: Websters Dictionary (01 Mar 1998) |
| polaris | <astronomy> The polestar. See North star, under North. Origin: NL. See Polar. Source: Websters Dictionary (01 Mar 1998) |
| polariscope | <instrument, optics> An instrument consisting essentially of a polarizer and an analyzer, used for polarizing light, and analyzing its properties. (28 Oct 1998) |
| polariscopic | <optics> Of or pertaining to the polariscope; obtained by the use of a polariscope; as, polariscopic observations. (28 Oct 1998) |
| polariscopy | <optics> The art or rocess of making observations with the polariscope. Source: Websters Dictionary (01 Mar 1998) |
| polarise | To put into a state of polarization. (05 Mar 2000) |
| polarised light | Light in which, as a result of reflection or transmission through certain media, the vibrations are all in one plane, transverse to the ray, instead of in all planes. (05 Mar 2000) |
| polariser | The first element of a polariscope that polarises the light, as distinguished from the analyzer, the second polarising element. (05 Mar 2000) |
| polarising microscope | <instrument> A microscope equipped with a polarising filter below and above the specimen which forms an image by the influence of specimen birefringence on polarised light; the polarising direction of the two filters is typically adjustable which, together with a graduated rotating stage, permits measurement of the angular value of different refractive indices in either biological or chemical specimens. (05 Mar 2000) |
| polaristic | Pertaining to, or exhibiting, poles; having a polar arrangement or disposition; arising from, or dependent upon, the possession of poles or polar characteristics; as, polariztic antagonism. Source: Websters Dictionary (01 Mar 1998) |
| polarity | <physics> Literally having poles (like a magnet), but used to describe cells that have one or more axes of symmetry. <cell biology> In epithelial cells, the polarity meant is between apical and baso lateral regions, in moving cells, having a distinct front and rear. Some cells seem to show multiple axes of polarity (which will hinder forward movement). (18 Nov 1997) |
| polarity of translation | Decrease in the synthesis of proteins specified by genes distal to the operator and to the site of a nonsense, frameshift, deletion or insertion mutation in an operon. A mutation which produces polarity is called a polar mutation or a polarity mutation. (12 Dec 1998) |
| polarizability | <chemistry> Of orbitals means that the electron cloud can be shifted towards a positive charge or away from a negative charge due to electrostatic attraction and repulsion. (09 Jan 1998) |
