    摘要： A multilayer reflector useable to reflect or transmit light over the visible wavelength range includes optically thick constituent layers. The optical thickness of the constituent layers through the thickness of the reflector defines a layer thickness profile. The layers are arranged so that the thickness profile has a tailored non-uniform distribution, such as a graded distribution or a randomized distribution. The layers desirably have an optical thickness in a range from about one to five or one to ten design wavelengths. The reflector can be a polarizer, reflecting only one normally incident polarization state, or a mirror, reflecting two normally incident orthogonal polarization states.

    摘要： A detector system, filter therefor, and method of making same is disclosed. The filter includes an interference element having a reflection band disposed primarily in the near infrared, and having a high transmission over most of the visible region. The filter also includes an absorptive element that absorbs light non-uniformly over the visible region. The filter when combined with a semiconductor photodiode or other suitable detector yields a detector system whose spectral responsivity closely matches the visual response of the human eye.

    摘要： The present application discloses optical elements for use in applications where high contrast is desirable. The optical elements comprise a multilayer optical film having a plurality of reflection bands at design wavelengths of incident light, wherein at least one of the reflection bands is a narrow reflection band, wherein each reflection band has a nominal spectral position at a design angle of incidence and wherein each reflection band shifts to a color-shifted reflection band for light incident at angles other than the design angles. The optical elements also comprise a wavelength selective absorber for absorbing at least one of the color-shifted reflection bands.
