11 Facts About Circular polarizer

1.

Simple linear Circular polarizer can be made by tilting a stack of glass plates at Brewster's angle to the beam.

2.

Wollaston prism is another birefringent Circular polarizer consisting of two triangular calcite prisms with orthogonal crystal axes that are cemented together.

3.

Since the electrons are free to move in this direction, the Circular polarizer behaves in a similar manner to the surface of a metal when reflecting light, and the wave is reflected backwards along the incident beam .

4.

For far-infrared optics, the Circular polarizer can be even made as free standing mesh, entirely without transmissive optics.

5.

Malus's law, which is named after Etienne-Louis Malus, says that when a perfect Circular polarizer is placed in a polarized beam of light, the irradiance, I, of the light that passes through is given by.

6.

The linearly polarized light leaving the linear polarizer is transformed into circularly polarized light by the quarter wave plate.

FactSnippet No. 1,386,625
7.

The transmission axis of the linear Circular polarizer needs to be half way between the fast and slow axes of the quarter-wave plate.

8.

Homogeneous circular polarizer passes one handedness of circular polarization unaltered and blocks the other handedness.

FactSnippet No. 1,386,627
9.

Homogeneous circular polarizer can be created by sandwiching a linear polarizer between two quarter-wave plates.

FactSnippet No. 1,386,628
10.

Specifically we take the circular polarizer described previously, which transforms circularly polarized light into linear polarized light, and add to it a second quarter-wave plate rotated 90° relative to the first one.

FactSnippet No. 1,386,629
11.

The linear Circular polarizer sandwiched between the quarter wave plates is oriented so that it will pass one linear polarization and block the other.
