Original Abstract Submitted
an electronic device may include a display system and an optical system that are supported by a housing. the optical system may be a catadioptric optical system having first, second, and third lens elements. the first lens element may have a convex surface and a concave surface. the convex surface may have less curvature than the concave surface. an anti-reflective coating may be formed on the convex surface. a partially reflective mirror may be interposed between the first and second lens elements and a reflective polarizer may be interposed between the second and third lens elements. alternatively, a partially reflective mirror may be interposed between the second and third lens elements and a reflective polarizer may be interposed between the first and second lens elements.
