IPC: G02B5/32
Filed: 1989-12-27
Abstract: PURPOSE:To reduce the attaching and adjusting process of a hologram element by forming a reflection hologram element in a vessel, to which a laser light source and a light receiving element are attached, as one body. CONSTITUTION:A resin is charged into the space between a vessel inside face mold 8 to which a glass plate 6, where a hologram pattern for hologram groove formation is formed on a part corresponding to a hologram groove forming part 2a, is fixed and a vessel outside face mold 7 to form a vessel 3 and a reflection hologram element 2 as one body. The laser light radiated from a laser light source and light receiving element unified unit 5 is reflected by the hologram element 2 and irradiates an optical information recording medium through a mobile lens part 1. The reflected light passes the mobile lens part 1 and is reflected by the hologram element 2 and is made incident on the light receiving element in the unit 5. Consequently, a tracking signal, a focusing signal, and an optical information signal are obtained. Thus, the attaching and adjusting process of the hologram element 2 is reduced.
