WGF™ Film-Based Wire Grid Polarizer

WGF^™ from Asahi Kasei is the film-based wire grid polarizer. Its Aluminum wire grid structure provides excellent polarization separation across a wide range of wavelengths, including visible (VIS), infrared (IR)and longer wavelengths. In comparison to absorptive polarizers, it also has excellent heat resistance.

In order to bring out the functions and effects of WGF™, quality of processing is an important point.Asahi Kasei is now providing the materials as fixed components, including initial evaluation samples, so that various customers can try and utilize themproperly.Please feel free to contact Asahi Kaseifor your desired size or any other requests.

Features of WGF^™

Reflective Polarization Film with Low Heat Absorption

Usable in both transmission and reflection use

Low AOI Dependence

Stable optical performance even at wide AOI such as PBS

Wide Effective Range from VIS to IR or More

The anti-reflection effect when using with IR image sensors has been used in several industrial fields

Excellent Reliability in High Temperature and Humidity Conditions

WGF™ can be used even in an environment where conventional polarizer cannot be used. Widely applied for automotive use & high brightness lighting.

Flexible and Excellent Processability

High workability such as cutting into complicated shapes, bonding to other materials, and even curved surface molding is possible. We can offer WGF™ as various components based on your requests.
