Abstract

The optical assemblies disclosed herein advantageously utilize a beamsplitting apparatus in association with (i) the illumination path or (ii) the collection path of a color measurement instrument. Thus, the beamsplitting apparatus may be configured to spectrally divide one or more initial beams of light to emit a plurality of resultant beams of light, wherein the optical assembly is configured to illuminate a target using at least a first and second of the plurality of resultant beams. Alternatively, the beamsplitting apparatus may be configured to spectrally divide light received from a target to emit a plurality of resultant beams of light, wherein the optical assembly is configured to detect at least a first and second of the plurality of resultant beams of light. Advantageously, each of the first and second resultant beams is a product of a distinct set of one or more spectral constraints exacted by the beamsplitting apparatus.
