Patent ID: 7483216

Claim:
An optical component comprising: a reflective substrate for receiving light beams on a illumination path and for selectively reflecting light beams on a projection path to be viewed or on alternate path which is not viewed; a first lens element having at least one substantially planar surface and at least one curved surface for focusing light; and a second lens element having at least one substantially planar surface and at least one exposed curved surface for focusing light on the reflective substrate, the at least one substantially planar surface of the first lens element being adjacent and substantially parallel to the at least one substantially planar surface of the second lens element to form a selectively reflecting interface, such that light on the alternate path strikes the planar surface of one of the lens elements on a path at an angle less than a known critical angle and is reflected away from the projection path, while light on the projection path strikes the planar surface of said one lens element on a path greater than the critical angle and is passed through the other lens element; wherein the curved surface of the first lens element deflects light beams in the illumination path toward the reflective substrate and focuses light beams in the projection path.
