WGF™ from Asahi Kasei is the very first 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
It can be used for both transmission and reflection.
Low AOI Dependence
Even at a wide AOI, such as PBS, optical performance is stable.
Wide Effective Range from VIS to IR or More
The anti-reflection effect when used along with IR image sensors is employed in various industrial fields.
Excellent Reliability in High Temperature and Humidity Conditions
WGF™ could be used in situations where a traditional polarizer is not possible. It is popular in high brightness lighting or automotive use.
Flexible and Excellent Processability
Cutting into complex shapes, connecting to other materials and curved surface molding are all possible processing options. It can be provided as a processed product.
