Compact projector for head-mounted displays

A waveguide configuration for conveying an image to an eye of a user in a near-eye display, the waveguide configuration comprising:

• a) a waveguide formed from transparent material and having a plurality of surfaces including two mutually parallel major surfaces, said waveguide supporting propagation of image light by internal reflection at said major surfaces;
• b) a coupling prism formed from transparent material, said coupling prism having an image input surface and a waveguide interface surface;
• and
• c) an aperture stop interface between said coupling prism and one of said surfaces of said waveguide, said aperture stop interface including:
• i. an optically transmissive region in which said waveguide interface surface is optically bonded to said one of said surfaces of said waveguide, and
• ii. non-transmissive lateral stops regions delimiting two opposing edges of said optically transmissive region.
