Syllabification: po·lar·im·e·ter
Pronunciation: /ˌpōləˈrimidər
 
/

Definition of polarimeter in English:

noun

An instrument for measuring the polarization of light, and especially (in chemical analysis) for determining the effect of a substance in rotating the plane of polarization of light.
Example sentences
  • A major difficulty in using microscopes for polarimeters is that most polarimeters purposely only collect light from a very small angle
  • For example, the effect of acids and salts on a solution of an optically active substance such as nicotine could be followed by observing the rotation of the plane of polarised light through a polarimeter.
  • PDR Chiral make advanced laser polarimeters, but their site not just a glorified sales pitch for their instruments, as is so often the case with commercial web sites.

Origin

mid 19th century: from medieval Latin polaris 'polar' + -meter.
