Abstract: The application of one or more multifunctional holographic optical elements (HOE's) (40, 16) to a photometric apparatus, and a spectrophotometer in particular, is disclosed. Fabrication methods for HOE's especially useful in the foregoing application result in holograms which perform several classical optical (i. e., light gathering and steering) functions. The HOE's so fabricated are useful in a detector mode (16) (i.e., to process light from an illuminated sample for analysis of some portion of its spectrum); in a source mode (40) (i.e., processing light from a source (51) to a focus on a sample); and a combination of source and detector modes.
