<p>An optical spectrum filtering device, e.g., color filter, having reduced angle dependence is provided that comprises an interference filter assembly comprising a high refractive index dielectric material, such as a Fabry-Perot based resonator structure. The filter assembly is capable of transmitting a portion of an electromagnetic spectrum into the dielectric material to generate a filtered output with a predetermined range of wavelengths that displays minimal angle dependence, when viewed from a range of incidence angles ranging from normal (0°) to 90°. Methods of making minimal angle dependent optical spectrum filters and reducing angle dependence for such devices are also provided.</p> |
