Abstract
Optical elements, such as windows for forward-looking, infrared radiation-receiving devices have at least one substantially flat surface adapted for exposure to incident radiation and, within such elements, one or more doped regions having predetermined, desired, non-flat shapes or having doping concentrations. These doped regions are adapted for exposure to the same incident radiation, and are also adapted to reflect, refract or scatter one or more predetermined, desired wavelengths of the incident radiation while transmitting other predetermined, desired wavelengths of the same incident radiation. Methods for making these devices include growing the doped regions on the preformed surface of optical element blocks; immersing such blocks in a molten bath of the material from which the dopant is made; and placing one or more doped inserts into a preformed region of an optical element block.
