Polarizers Selection Guide

Human eyes have no ability to perceive the polarization of light.
Also, the most of the optical detectors do not carry sensitivity of the polarization.
For this reason, filters that selectively transmit the light with specific polarization or optics
that can change the polarization state become necessary.
In this page, a guidance is provided for finding a suitable application for the variety of polarization optics.

Type of Polarizers Type of Waveplates Products Features Accuracy Application
Plastic Sheet Polarizers (USP) Low cost, Lightweight Variable adjustment of laser intensity
Mica Waveplates
(WPM)
Substitute use as optical retarder
Substitute use as phase sensitive color plate (visually intensify the retardance distribution)
Observation of stress (birefringence) distribution
Polarizing Beamsplitters (PBS) Combine or separate the polarized beam A simple polarization experimental setup, Polarizing optical systems (Variable attenuator, Polarization interferometer, Optical isolator)
Visible Sheet Polarizers
(SPF)
Provide stationary linear polarization light in visible region
Quartz Waveplates
(WPQ)
Provide exact optical retardation for each wavelength of laser
Glan Thompson Prisms
(GTPC)
Provide linearly polarized light with excellent extinction ratio in visible region Polarization measurements (Extinction ratio, Optical retardation)
Fresnel Rhombs
Retarders
(FRB)
Provide stationary optical retardation in a broad wavelength range.
