What are (dichroic) polarizer [polarizing filter] meant to be?

The phenomenon of polarization of light is based on the waveform character of the light. Light is a transverse electromagnetic wave, with electric and magnetic fields oscillating normal to the direction of propagation.

A polarizer filters out those fractions of light which oscillate in parallel to the filter centerline of the polarizer. If, for example, the orientation of an electromagnetic wave is 45 relative to an ideal polarizer's direction of filtering, it will transmit an electromagnetic wave which, while the direction of oscillation is in parallel to the filtering direction (polarization axis), has 50% of the intensity of incident light. If, however, the angle formed between the wave and the polarization axis is 90, light is not transmitted any more. In contrast, with the angle being 0, the wave would travel through the polarizer without any restriction.



This phenomenon is not just limited to the visible wavelength range (light visible by the human eye, also known as the rainbow spectrum); it even does occur throughout the electromagnetic spectrum, hence also in the infrared (IR) and the ultraviolet (UV) ranges. Each of the varied technical uses to which this phenomenon may be put calls for a polarizer to be employed for the particular wavelength range. In addition to the optical parameters, there are requirements to be met in terms of geometric dimensions, resistance and useful life.
