The CP42HE circular polarizer is created by laminating the XP42 linear polarizer to the high contrast WP140HE ¼ wavelength retarder sheet. The process results in one of the best circular polarizers available on the market, offering the highest contrast and maximum light transmission for the most demanding of applications.
- Increasing the contrast of LCD and OLED panels
(in fact, all reflective surfaces)
- Stress analyzers

The polarizer is left circular (LH). Right circular 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.
