ABSTRACT:
A spectral filter for use in optical systems receiving field-of-view (FOV) optical beams at differing angles refracts all FOV beams onto a single plane focal surface. The spectral filter comprises a combination of lens having varied thicknesses incorporated into a single filter unit. Each thickness, or step, of the spectral filter corresponds to a different one of the received FOV beams.
