Abstract: There is provided an optical system, including a light-transmitting substrate (20) having at least two external major surfaces and edges, an optical element for coupling light waves into the substrate (20) by internal reflection, at least one partially reflecting surface located in the substrate (20), for coupling light waves out of the substrate (20), at least one transparent air gap film (110) including a base (112) and a hyperfine structure (111) defining a relief formation, constructed on the base, wherein the air gap film is attached to one of the major surfaces of the substrate (20), with the relief formation facing the substrate (20) defining an interface plane (58), so that the light waves coupled inside the substrate (20) are substantially totally reflected from the interface plane (58).
