OPTICAL COMPONENT AND MANUFACTURING METHOD THEREFOR

摘要

PROBLEM TO BE SOLVED: To provide an optical component centered with sufficient eccentric precision, while suppressing a manufacturing cost from increasing, and to provide a manufacturing method therefor.

SOLUTION: An optical lens 1 is provided with a first lens face 12B of a light incident face, and a second lens face 11 as a second face opposite to the first lens face 12B. The first lens face 12B has an aspherical shape, and the second lens face 11 has a spherical face having a curvature radius R1. The optical lens 1 has respectively a point P2and a point P1where a value of an inclination function D defined by Expression (1) is 0.1 or more, on the first lens face 12B and the second lens face 11, in a cross section including an optical axis α of the optical lens 1.
