polarimetern.

Brit.

/ˌpəʊləˈrɪmᵻtə/, U.S.

/ˌpoʊləˈrɪmədər/

Origin: Formed within English, by compounding; probably modelled on a French lexical item. Etymons: polarization n., -meter comb. form².

Etymology: < polari- (in polarization n.) + -meter comb. form² (compare -imeter comb. form), probably after French polarimètre (1841). Compare earlier polariscope n.

Science.

An instrument for measuring the degree of polarization; esp. one for determining the amount of rotation of the plane of polarization by a substance through which polarized light passes.

1843 Abstr. Papers Royal Soc. 1837–43 4 306 The following papers were read, viz. 1. ‘On the Compensations of Polarized Light, with the description of a Polarimeter for Measuring Degrees of Polarization.’ By Sir David Brewster.

1869 Eng. Mech. 24 Dec. 357/3 The detection..may be effected with the polarimeter, as pure glycerine has no action upon polarised light.

1899 J. Cagney tr. R. von Jaksch Clin. Diagnosis (ed. 4) v. 162 The rotatory power of each of the four fluids is ascertained by means of the polarimeter.

1979 Sci. Amer. May 63 (caption) Polarization is monitored..by polarimeters that measure the left-right asymmetry in scattering events.

1996 Nature 15 Aug. 588/1 We have developed an imaging polarimeter system that can routinely record the Sun's spectrum with a precision of 10⁻⁵ in the degree of polarization.
