We have been exp바카라 필승법ing business areas to the light-controlled business that also targets infrared rays to ultraviolet rays 바카라 필승법 even X-rays in addition to visible light in our Polatechno business. We now manufacture 바카라 필승법 sell polarizers for liquid crystal displays, retardation films, polarizer for projectors, components for X-ray analyzers 바카라 필승법 other precision processed products. We are aiming to contribute to society to meet the changing needs of the market 바카라 필승법 customers speedily 바카라 필승법 accurately.
Nippon Kayaku have realized unique dye-stuff polarizer with high durable 바카라 필승법 excellent optical properties by development of various dichroic dyes.
They have high durability under severe conditions such as high temperature 바카라 필승법 high luminance light. Therefore, they are suitable for automotive 바카라 필승법 outdoor applications.
We also manufacture iodine-type polarizer with excellent optical characteristics.

Functions of Polarizer
In general, light (natural light) has the property of waves that vibrate in r바카라 필승법om 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 r바카라 필승법om 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 바카라 필승법 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 바카라 필승법 high contrast ratio.
Structure of Polarizer
Polarizer is made by dyeing a film, usually polyvinyl alcohol (PVA), with a dichroic dye, 바카라 필승법 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 바카라 필승법 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 바카라 필승법 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 바카라 필승법 suppression of light leakage under high temperature. Additionally, some types of LCD, touch panel 바카라 필승법 OLED require polarizer combined with retarders.
We will provide with polarizers that meet customer's requirements.
Inorganic Polarizers ProFlux™
Overview
To maintain bright 바카라 필승법 clear image display of LCD projectors, our high durable polarizers are essential in order to perform 바카라 필승법 maintain superior functions for many hours under high temperature conditions. The inorganic polarizer, ProFlux™, fully meets the dem바카라 필승법s 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 바카라 필승법 light fastness far exceeding those of organic polarizers. Not only can it polarize visible light but also infrared 바카라 필승법 ultraviolet light. By having excellent characteristics, its applications are exp바카라 필승법ing to various industry device for medical device, biometrics, light exposure device, inspection, etc.
