Optical assembly for reflective light valves |
| abstract |
The invention relates to a compact polarization insensitive prism assembly for projection display systems using reflective light valves. The systems comprising a trichroic prism assembly of three coated prisms, and a specially shaped, trapezoidal in the embodiment, beam splitter. The angles of the prisms are optimised for best colour separation and recombining with the least polarization insensitivity. The assembly forms a compact and spectrally efficient optical arrangement for reflective LCD projectors. |
