A linear polarizer may be formed on the concave surface. A quarter wave plate may receive light from the linear polarizer. A catadioptric lens may have first and second lens elements. The first lens element may have first and second opposing surfaces. The second lens element may have opposing third and fourth surfaces. The first surface may be convex and may face the display. The fourth surface may be concave. The second surface may be concave. The third surface may be convex and may match the second surface. An additional quarter wave plate may be formed as a coating on the third surface. A partially reflective coating may be formed on the first surface. A reflective polarizer may be formed as a coating on the fourth surface.
