Claim 0:
1. An optical device comprising:
a first prism including:
a first light-wave entrance surface, a second light-wave entrance surface, and a light-wave exit surface, 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; and

a second prism including:
a first light-wave entrance surface, and a second light-wave entrance surface associated with the light-wave exit surface of the first prism, and
a second dichroic beamsplitter configuration deployed within the second prism on a plane oblique to at least one of the light-wave entrance surfaces 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,

the first dichroic beamsplitter configuration transmitting light at a wavelength of a first color, polarized in the first polarization state with regards to the first dichroic beamsplitter configuration, and reflecting light at a wavelength of a second color, polarized in the first polarization state with regards to the first dichroic beamsplitter configuration, and
the second dichroic beamsplitter configuration transmitting light at a wavelength of the first color and light at a wavelength of second color, polarized in the second polarization state with regards to the second dichroic beamsplitter configuration, and reflecting light at a wavelength of a third color, polarized in the first polarization state with regards to the second dichroic beamsplitter configuration.
