Functions of Polarizer

In general, light (natural light) has the property of waves that vibrate in random directions. A polarizer is deemed as a kind of filter that has the function to pass the light that vibrates in a specific direction, not light that vibrates in random directions.
 As shown in the figure as follows, suppose that a polarizer is a fine filter that has lattices arranged in one specific direction. Light that has parallel to light transmittance axis can pass through the lattices, but light in another direction (light absorption axis) doesn't pass through. Thus, light can be set to one direction by passing through the filter (polarizer).

There are three important optical properties in polarizer: transmittance, polarization efficiency and hue. The theoretical limit value of polarization efficiency in polarizer is 100% at 50% transmittance. By realizing the performance of the polarizer closer to the theoretical limit value, the polarizer achieves high performance display such as LCDs with high brightness and high contrast ratio.

Structure of Polarizer

Polarizer is made by dyeing a film, usually polyvinyl alcohol (PVA), with a dichroic dye, and then stretching the film to orient the dichroic dye within the film.

Polarizer is a film with polarizing properties in which dichroic dyes are oriented and absorb light vibrating in the direction, allowing another direction light in a certain vibration direction to pass through.
 In general, in order to improve mechanical properties, polarizer is supported by films such as TAC films and additional protective films.

Various fuctions are added on polarizer. In addition to polarizing properties, polarizer is required to have functions such as anti-reflection, anti-scratch and suppression of light leakage under high temperature. Additionally, some types of LCD, touch panel and OLED require polarizer combined with retarders. We will provide with polarizers that meet customer's requirements.

Inorganic Polarizers ProFlux™


To maintain bright and clear image display of LCD projectors, our high durable polarizers are essential in order to perform and maintain superior functions for many hours under high temperature conditions. The inorganic polarizer, ProFlux™, fully meets the demands for severe durability that are increasing year by year.
 Made by forming an aluminum film on a glass wafer with fine slits, the ProFlux™ provides required polarizer performance. This gives ProFlux™ the durability and light fastness far exceeding those of organic polarizers.
 Not only can it polarize visible light but also infrared and ultraviolet light. By having excellent characteristics, its applications are expanding to various industry device for medical device, biometrics, light exposure device, inspection, etc.
