WGF™ IR Polarizing Camera Filter by Asahi Kasei

The WGF^TM IR polarizing camera filter from Asahi Kasei has been specifically developed with WGF^TM, film-based wire grid polarizer. WGF^TM 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.

WGF^TM 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 WGF^TM panels for polarizing light sources. By using WGF^TM panels to polarize the light source, more effective observations can be achieved. WGF^TM 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.
