Complete Solutions
-
The photoelastic modulator provides unparalleled sensitivity in both polarization generation and polarization measurements. However, there are many non-PEM components in most polarization experiments that can adversely affect your results. The proper selection of detectors, demodulators, light sources and polarizers is crucial to obtaining the quality results that you need and that the PEM makes possible.
