ABSTRACT:
An infrared polarizer has a transparent substrate on which a pattern of spaced metal stripes is deposited. The stripe thickness is approximately equal to at least the stripe spacing which results in a substantial increase of the polarization contrast as compared to that of conventional polarizers having thinner stripes.
