Circular polarisers

What are you looking for in Stock?

Circular polarizer

Sheet polarizers are comprised of a linear polarizer cemented to a quarter wave plate, therefore polarizing the output light. If light passes through the polarizer and is reflected back from a mirror, the light that now enters the linear polariser component is polarised at right angles to the direction it will be passed and therefore will be absorbed. However the un-polarised light from the reflecting side will pass with a 50% transmission. This reduces the impact of ambient light on data displays, LCD screens or meters. Knight Optical stock replacement HNCP37 material offered in both non-glare and standard clear finish. These are available in left and right handed options.

Typical applications for HNCP37 polarizers include improved viewability for emissive displays and electro luminescent applications. Field emissive displays, cathode ray tubes, light emitting diodes, organic light emitting diodes all benefit from HNCP37 circular polarizers.
