polarimeter
(pəʊləˈrɪmɪtə(r))
[f. med.L. polāri-s polar (with reference to polarization) + -meter.]
A form of polariscope for measuring the amount of rotation of the plane of polarization, or the amount of polarized light in a beam.
| 1864 in Webster. 1869 Eng. Mech. 24 Dec. 357/3 The detection..may be effected with the polarimeter, as pure glycerine has no action upon polarised light. 1897 Allbutt's Syst. Med. III. 214 Grape-sugar deflects polarised light to the right, and upon this is based a method of estimation by means of a somewhat expensive instrument called a polarimeter. 1899 J. Cagney tr. Jaksch's Clin. Diagn. v. (ed. 4) 162 The rotatory power of each of the four fluids is ascertained by means of the polarimeter. |
Hence polarimetric (pəʊlærɪˈmɛtrɪk) a., of or pertaining to a polarimeter or polarimetry; polariˈmetrically adv.; polaˈrimetry, the art or process of measuring or analysing the polarization of light or other electromagnetic radiation.
| 1864 Webster, Polarimetry. 1899 J. Cagney tr. Jaksch's Clin. Diagn. i. (ed. 4) 88 The polarimetric test may be applied. Ibid. v. 163 This method..requires a very accurate polarimeter, light polarimetric examinations, and a highly-complicated calculation. 1930 [see Foucault]. 1937 Jrnl. Org. Chem. II. 431 The mutarotation of glucose was measured polarimetrically, in 200 mm. tubes. 1973 Jrnl. Biol. Chem. CCXLVIII. 4165/1 Each solution was then diluted to 12 ml..and the further progress of the reaction followed polarimetrically. 1975 Nature 14 Aug. 537/1 In the past, the best-known argument for X-ray polarimetry has been that it is often symptomatic of non-thermal synchrotron-type emission. |
