1. A multichannel beamsplitter optical system, comprising:
a light collection system for collecting light from a scene and producing a converging beam of light;
a first cube beamsplitter;
a second cube beamsplitter bonded to the first cube beamsplitter; and
an input wavefront compensator bonded to the first cube beamsplitter and having a convex curved surface to match a wavefront of the converging beam of light received from the light collection system; and
a first output wavefront compensator having a concave surface matching a wavefront converging beams of light exiting the second cube beamsplitter.
