Abstract
An optical system and method for providing a visible light beam with a desired characteristic includes a visible light source producing a visible light beam defining an optical train. An optical element is disposed in the optical train to create a modified beam, and that is capable of introducing an undesired characteristic that continuously transitions across at least a portion of the modified beam. A wire-grid polarizer is disposed in the optical train, and has a plurality of elongated elements with at least a portion that continuously transitions to a different characteristic. The wire-grid polarizer is positioned and oriented in the optical train with the different characteristic corresponding to the undesired characteristic of the modified beam to obtain a visible light beam with a desired characteristic substantially across the visible light beam.
