ABSTRACT:
A holographic filter comprises a volume hologram recorded with Bragg surfaces for use in spectroscopic and spectral splitting applications. The Bragg planes in the holographic filter can be recorded to satisfy virtually any design constraint imposed upon the filter such as Raman, Lippmann, non-Snellian (slanted), curved, and multiplexed spectral filters. The holographic filter achieves maximal reduction of secondary maxima and sidelobes and obtains large wavelength selectivities, and varied grating constants.
