Claim:
1. An optical apparatus, comprising: a plurality of prisms assembled together to form a single body, each prism having a plurality of faces, at least one of the faces of each prism being a mating face, each mating face being coupled to a corresponding mating face of another of the prisms, a first pair of the coupled mating faces defining a first interface, a second pair of the coupled mating faces defining a second interface, the first interface being parallel to the second interface, the first interface and the second interface being positioned within the single body, the plurality of prisms defining an exterior surface of the single body, the exterior surface including a first window, a second window, and a third window, the first window being configured to transmit first photons having a first wavelength and second photons having a second wavelength in and out of the single body, the second window being configured to transmit the first photons in and out of the single body, and the third window being configured to transmit the second photons in and out of the single body, the first interface including a first optical feature and a third optical feature, and the second interface including a second optical feature, wherein the first optical feature is configured to transmit the first photons and the second photons through the first interface and between the first window and the second optical feature, the second optical feature is configured to: (i) transmit the first photons through the second interface and between the first optical feature and the second window, and (ii) reflect the second photons between the first optical feature and the third optical feature, and the third optical feature is configured to reflect the second photons between the second optical feature and the third window.
