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.

In observation utilizing polarization, it is crucial to polarize the light source as well. We also offer WGFTM panels for polarizing light sources. By using WGFTM panels to polarize the light source, more effective observations can be achieved. WGFTM has high heat-resistance, therefore it is suitable for high-brightness halogen lighting. In addition to standard models, custom products are also available to solve your issues.
