    摘要： The present disclosure relates to an optical member in which an antireflection concave-convex structure for suppressing reflection of light is provided on its surface, and an optical system, an optical unit and an optical device each including the optical member.The present disclosure provides an optical member in which the generation of reflection light and diffraction light is sufficiently suppressed and which can be fabricated in a simple manner.A antireflection concave-convex structure (15) for suppressing reflection of light, formed of filiform convex portions (16) regularly arranged, is provided on an interior surface (1a) of a lens tube (1). The antireflection concave-convex structure (15) is configured so that an angle between a normal vector of an incident plane of the light whose reflection is to be suppressed and a vector connecting respective apexes of adjacent two of the structure units at the incident surface is 60 degrees or less.

    摘要： A surface emitting apparatus and image display apparatus using this surface emitting apparatus that enables improved luminance uniformity and smaller apparatus sizes. The surface emitting apparatus has a light source section that emits light, a light guide plate that guides light incident from an inlet face such that the light is emitted from a surface of an outlet face and a scanning section that scans the light emitted from the light source section on the inlet face of the light guide plate. The image display apparatus has the surface emitting apparatus and a display panel that is arranged on a side of the outlet face of the light guide plate.

    摘要： A light-emitting device includes a light-emitting element 110; and a lens section 132 covering over the light-emitting element 110. The lens section 132 includes an entrance surface S1 on which light from the light-emitting element 110 is incident; an exit surface S2 from which the light incident on the entrance surface S1 is emitted; and an optical axis L extending so as to penetrate the entrance surface S1 and the exit surface S2. A concave section 132a is formed in an area of the exit surface S2, which contains the optical axis L, and two flat sections 132b are formed so as to face each other across the optical axis L. The exit surface S2 defines an upwardly-protruding curved surface formed between the two flat sections 132b, and the optical axis L is coincidence with a reference optical axis of the light-emitting element 110.
