The accuracy and precision of polarimetric analyses, as with many optical methods of analysis, can be significantly enhanced through the use of lasers as sources of illumination. The properties that give lasers advantage over conventional sources for polarimetry are high brightness, stable intensity, spatial coherence, and monochromaticity. In order to appreciate the advantages to both visual and photoelectric polarimetry we will first briefly discuss typical methods of measurement, then present experimental comparisons of lasers and conventional lamps.
