polarizern.

Brit.

/ˈpəʊlərʌɪzə/, U.S.

/ˈpoʊləˌraɪzər/

Forms: 1800s– polariser, 1800s– polarizer.

Origin: Formed within English, by derivation. Etymons: polarize v., -er suffix¹.

Etymology: < polarize v. + -er suffix¹. Compare French polariseur (1836 in sense 1).

1. A plate or prism for polarizing light or other radiation in a scientific instrument, esp. the light entering a polariscope or polarimeter (contrasted with analyser).

1837 H. F. Talbot in Philos. Trans. (Royal Soc.) 127 25 When the polarizers* are crossed, we observe the following phenomenon. [Note] *By this term..I here designate the polarizing and analysing prisms of single-image calcareous spar, or the plates of tourmaline which may be employed in their stead.

1854 B. Powell Pereira's Lect. Polarized Light (ed. 2) 50 Either part..may be used as polarizer or analyzer; but whichever we use as the polarizer, the other then becomes the analyser.

1863 E. Atkinson tr. A. Ganot Elem. Treat. Physics §638 Every instrument for investigating the properties of polarised light consists essentially of two parts, one for polarising the light, the other for ascertaining the fact of light having undergone polarisation The former part is called the polariser, the latter the analyser.

1879 F. Rutley Study of Rocks vii. 48 The polariser should revolve with perfect freedom.

1960 IRE Trans. Microwave Theory 8 520/1 This circular polarizer consists of three cascaded half- and/or quarter-wave birefringent plates.

1975 Nature 10 Jan. 98/1 The illuminating light, from a 100 W FCR tungsten-halogen bulb, traversed a heat filter and two plane polarisers.

2003 Photonics Spectra Sept. 23/2 The 810-nm photons were then separated and routed to receiver stations equipped with polarizers and single-photon-counting avalanche photodiodes.

2. A photographic or optical filter that polarizes light passing through it, used chiefly for reducing reflections and improving contrast.

1935 Jrnl. Soc. Motion Picture Engineers 25 70 A second polarizing device placed in the path of the ray leaving the first polarizer, may or may not transmit the plane polarized ray.

1965 Pop. Photogr. June 84/1 Thanks to the gain in popularity of the SLR, the polarizer has become one of the most practical filters around.

1991 Photo Answers July 59/2 For these types of shots a polariser is ideal, saturating the colours of the sky and the costume a treat.

2002 Outdoor Photographer Dec. 92/2 Like all polarizers, the Gold-N-Blue has its greatest effect when the sun is at a right angle to the axis of your lens and filter.
