Optical Devices and Systems with Dichroic Beamsplitter Color Combiner

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;
• a second prism including:
• a first light-wave entrance surface, a second light-wave entrance surface, and a light-wave exit surface, 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 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 that produces red light that is s-polarized with regards to the first dichroic beamsplitter configuration;
• a second source of polarized light that produces blue light that is s-polarized with regards to the first dichroic beamsplitter configuration;
• and
• a third source of polarized light that produces green light that is s-polarized with regards to the first dichroic beamsplitter configuration, the first dichroic beamsplitter configuration transmitting the polarized red light and reflecting the polarized blue light so as to output polarized mixed light though the light-wave exit surface of the first prism, the polarized mixed light being a mixture of the polarized red light and the polarized blue light,
• the second dichroic beamsplitter configuration transmitting the polarized mixed light and reflecting the polarized green light so as to output mixed light though the light wave exit surface of the second prism, the mixed light being a mixture of the polarized red light, polarized blue light and polarized green light.
