CP42N CIRCULAR POLARIZER

The CP42N circular polarizer is comprised of a XP42 linear polarizer and a  1/4 wave retarder whose slow and fast axis are at 45° to the axis of the polarizer. The CP42N neutral grey polarizer provides contrast enhancement and reflection suppression in moderately high luminance environments.

Application areas:

  • Increasing the contrast of LCD and OLED panels
    (in fact, all reflective surfaces)
  • Stress analyzers
  • Sensors

The polarizer is left circular (LH). Right circular (RH) polarizers can be produced if required.

Customized cuts on demand.
The direction of polarization is parallel to the first-mentioned dimension.
Protective films on both sides should be removed before using the polarizers within your application.
We reserve the right to change the technical specifications at any time.
