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

Definition of polarimeter in English:


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.


Pronunciation: /pōˌlarəˈmetrik/
Example sentences
  • Several difficulties arise from using a conventional light microscope for polarimetric studies.
  • We put these principles to work when we designed and built a waveplate for a spectropolarimeter and polarimetric filtergraph being built by Lockheed Martin Solar and Astrophysics Laboratory (Palo Alto, CA) under contract to NASA.
  • In the lab, however, people are now using more polarimetric techniques because they let them calculate all polarization states.
Pronunciation: /ˌpōləˈrimətrē/
Example sentences
  • Precision control of polarization is increasingly important in disciplines such as solar polarimetry, optical communications, biomedical imaging, military target identification, chemical analysis, and wavelength filtering.
  • In addition to polarimetry, analyzing the spectrum of a Type Ia supernova during the rising part of its light curve can reveal specific information about its elemental composition.
  • We studied polarimetry with wide-band filters and a simple instrument that took us six months to calibrate.


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