Abstract

See full text

An optical apparatus capable of correcting field curvature easily, a method for manufacturing the optical apparatus, and a headlight including the optical apparatus. A lens, a plurality of solid-state light sources, and a substrate on which the solid-state light sources are mounted. The substrate includes a base material, which is rigid, and a mount surface, which is formed on the base material in a curved surface shape that substantially matches a focal plane shape of the lens, and on which a circuit pattern is formed. The solid-state light sources are mounted on the mount surface, and the substrate is positioned with respect to the lens such that a position of a focal plane of the lens substantially coincides with emission surfaces of the solid-state light sources, and thus field curvature can be easily corrected.
