Abstract
An optical element has layers formed on a substrate, including alternating first and second layers having first and second refractive indices, nand nthat exhibit a spectral characteristic, providing, for incident light at a predetermined wavelength and directed toward the optical element within a range of angles bounded by first and second incident angles θand θ, between 0 and 80 degrees and differing by at least 1 degree, substantially linear polarization-averaged attenuation of the incident light energy wherein, for any incident angle θbetween θand θ, Aθis the corresponding polarization-averaged attenuation, and wherein the polarization-averaged attenuation at Aθat angle θis less than or equal to an optical density value of 0.2 and the polarization-averaged attenuation Aθat angle θexceeds an optical density value of 4.
