Angle of incidence restriction for optical filters

Abstract:

A filter may include a first component filter associated with a first angle shift and a first passband. The filter may include a second component filter associated with a second angle shift and a second passband, wherein the first angle shift, the first passband, the second angle shift, and the second passband are configured to make the filter transmissive to a spectral range of light at a first angle of incidence and reflective to the spectral range of light at a second angle of incidence.
