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.

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.
