Abstract
A beamsplitter includes an optical substrate with a first surface configured to receive a beam of multi-spectral light, to reflect a first band of the multi-spectral light and to transmit a second band of the multi-spectral light through the optical substrate to be emitted from a second surface of the optical substrate opposite the first surface. The second surface is a freeform surface. A system includes a telescope configured to focus multi-spectral light into a beam. The system also includes a beamsplitter as described above optically coupled to the telescope so the first surface of the beamsplitter is configured to receive the beam of multi-spectral light from the telescope.
