Abstract
Optical systems including an image surface and a stop surface are described. First second and third optical lenses, a partial reflector, a multilayer reflective polarizer and a quarter wave retarder are disposed between the image surface and the stop surface. A plurality of major surfaces are disposed between the image surface and the stop surface with each major surface convex toward the image surface along orthogonal first and second axes. At least six different major surfaces have six different convexities.
