Claim 17:
18. An optical device comprising:
a prism assembly including:
a first external surface, a second external surface, and a third external surface, wherein the first, second and third external surfaces are mutually orthogonal, and wherein a first light-wave entrance surface is formed on at least a portion of the first external surface, a second light-wave entrance surface is formed on at least a portion of the second external surface, and a third light-wave entrance surface is formed on at least a portion of the third external surface, and
a first dichroic beamsplitter configuration deployed within a first portion of the prism assembly on a plane oblique to at least one of the first or second light-wave entrance surfaces,
a second dichroic beamsplitter configuration deployed within a second portion of the prism assembly on a plane oblique to the third light-wave entrance surface such that light in a first polarization state with regards to the first dichroic beamsplitter configuration is in a second polarization state with regards to the second dichroic beamsplitter configuration;

a first source of polarized light, associated with the first light-wave entrance surface, that produces light of a first color in a first polarization state with regards to the first dichroic beamsplitter configuration;
a second source of polarized light, associated with the second light-wave entrance surface, that produces light of a second color in the first polarization state with regards to the first dichroic beamsplitter configuration; and
a third source of polarized light, associated with the third light-wave entrance surface, that produces light of a third color in the first polarization state with regards to the first dichroic beamsplitter configuration,
wherein the first dichroic beamsplitter configuration is configured to transmit light, at a wavelength of the first color, that is polarized in the first polarization state with regards to the first dichroic beamsplitter configuration, and reflect light, at a wavelength of the second color, that is polarized in the first polarization state with regards to the first dichroic beamsplitter configuration, and
wherein the second dichroic beamsplitter configuration is configured to transmit light, at a wavelength of the first or second color, that is polarized in the second polarization state with regards to the second dichroic beamsplitter configuration, and reflect light, at a wavelength of the third color, that is polarized in the first polarization state with regards to the second dichroic beamsplitter configuration.
