Circular Polarizers (CP42HE and CP42HER) are ideal for reducing glare in a variety of imaging applications or for increasing the visibility of displays in bright environments. These circular polarizers feature excellent transmission of visible light from 400 – 700nm. The plastic substrate offers increased durability, while the film substrate offers increased flexibility and can be cut to fit an application’s needs. Left-handed (CP42HE) and right-handed (CP42HER) polarization directions are available. The best performance will be achieved at 560nm and polarization may become more elliptical the further the deviation from this recommended wavelength.
