Claim 15:
16. An optical device comprising:
a first prism including:
first and second light-wave entrance surfaces, and
a first dichroic beamsplitter configuration deployed within the first prism on a plane oblique to at least one of the light-wave entrance surfaces;

a second prism including:
a light-wave entrance surface, and
a second dichroic beamsplitter configuration deployed within the second prism on a plane oblique to the first light-wave entrance surface of the second prism and 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 of the first prism, 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 of the first prism, that produces light of a second color in the first polarization state with regards to the first dichroic beamsplitter configuration;
a third source of polarized light, associated with the first light-wave entrance surface of the second prism, that produces light of a third color in the first polarization state with regards to the second dichroic beamsplitter configuration,
wherein light produced by the first source of polarized light is transmitted by the first dichroic beamsplitter configuration and transmitted by the second dichroic beamsplitter configuration, and wherein light produced by the second source of polarized light is reflected by the first dichroic beamsplitter configuration and transmitted by the second dichroic beamsplitter configuration, and wherein light produced by the third source of polarized light is reflected by the second dichroic beamsplitter configuration.
