Title: Focus detector
Inventor: KUSAKA YOSUKE
IPC: G03B13/36
Filed: 1996-09-02
Abstract: PROBLEM TO BE SOLVED: To accurately detect a focus by preventing stray light from occurring as for the focus detector of a camera. SOLUTION: An optical system block is formed by integrally molding a condenser lens 21 and image reforming lenses 23 and 24 out of a transparent plastic material. Then, a reflection mirror 22 is formed on the deflection surface 48 of the optical system block. Besides, plural light shielding grooves 50 coated with a light shielding film are formed on the outside circumferential surface of the optical system block. Thus, since light other than luminous flux transmitted through the lens 21 and advanced straight toward the lenses 23 and 24 almost in parallel with an optical axis is absorbed by the grooves 50, the stray light is prevented from occurring and the focus is accurately detected.
