Definition of polarizer
Aug 15, 2018
In order to obtain polarized light, it is usually necessary to use some devices, which are mainly divided into the following types:
1. Reflective type:
When light is incident on the glass surface, its reflected light will be partially polarized. Using the continuous inverse of multiple layers of glass
The effect of the shot can be used to convert non-polar light into linear polarized light.
2. Complex plication type:
When two calcite crystals are joined, the incident light is split into two polarized lights called normal light and extraordinary light.
3. Dichroic microcrystalline form:
The microcrystals with dichroism are regularly adsorbed and arranged on a transparent sheet, which is the first time artificially
A polarizing film method.
4. Polymer dichroic type:
Using a polymer film with good polarization, the molecules in the film are oriented, and then the dichroic substance is adsorbed.
The adsorptive polarizers of this type are in the form of tablets or sheets or films. Therefore, it is also commonly referred to as a Polarizing Plate or Sheet or a Polarizing Filter
