    Abstract: An optical system includes a display, at least one lens, and at least one of a partial reflector and a reflective polarizer. The optical system forms a virtual image of an image emitted by the display for viewing by an eye. The emitted image includes a plurality of cones of image light. Each cone of image light propagates from a different corresponding location on the emitted image and includes a central light ray propagating along a central axis, such that in each of orthogonal first and second planes that include the central axis, an intensity distribution of the cone of image light as a function of angle relative to the central axis includes a substantially flat peak having a full width of at least 15 degrees across which the peak changes by less than about 20%, and a corresponding fullwidth at half maximum that is less than about 60 degrees.
