LIGHT-SHIELDING PLATE ADAPTED TO LENS |
摘要 |
A light-shielding plate adapted to a lens is provided, which includes a light-shielding body, a light through hole penetrating through a center of the light-shielding body and at least one identification region penetratively disposed at a periphery of the light-shielding body. One of the at least one identification region includes a straight edge located at a boundary of the light-shielding body. The light-shielding plate satisfies: Rs/R≧0.8, where R is a radius of the light-shielding body, and Rs is the shortest distance between the identification region located closest to the light through hole and a circle center of the light through hole. |
