WGF™ IR Polarizing Camera Filter by Asahi Kasei

The WGFTM IR polarizing camera filter from Asahi Kasei has been specifically developed with WGFTM,  film-based wire grid polarizer. WGFTM displays a high polarization separation performance in an extensive range of wavelengths, not only VIS but IR or longer.

This camera filter could be utilized in the near-infrared rays, even while having a wavelength range that is more than 1,000 nm. It has demonstrated great success as an anti-reflection filter in several inspections and imaging fileds, including sorting machines, biometrics, Printed Circuit Board inspection, fundus/Retinal examination tools, machines, etc.

This filter can be comfortably fixed to the users’ camera as it is. By rotating a rotator frame, users can adjust the polarization axis in an easy and free manner.

WGFTM IR polarizing camera filter guarantees a solution for users’ applications.
