3 Terms and Definitions
The following terms and definitions apply to this document.
3.1
Polarizer polarizingfilm
Also known as Polaroid. The natural light is converted into the polarizing optical element. The main piece of the original light, protective film, pressure sensitive adhesive layer, and other features
Optical film laminated optical film composite materials. The main part of the original light sheet, which consists of PVA film (polyvinyl alcohol film) and the upper and lower
A layer of a TAC film (triacetyl cellulose film) composition.
3.2
Optical properties opticalproperty
Optical properties including transmittance of the polarizer T, the degree of polarization P, hue H.
3.2.1
The degree of polarization (P) degreeofpolarization
It represents the degree of polarization of polarized light physical.
3.2.2
Transmittance (T) transmittance
Polarizing beam before and after the specific energy, expressed as a percentage. Transmittance is divided into monomers (single) transmittance, parallel (paralel)
Transmittance and perpendicular (orthogonal) transmission.
Monomer transmittance (Ts). beam transmittance measured by a monolithic polarizer.
