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.
