Abstract

A light-shielding element, including an object-side mechanical surface facing an object side, an image-side mechanical surface facing an image side, an inner-side surface facing an optical axis, and an outer-side surface facing away from the inner-side surface. The light-shielding element further includes at least one cut. The at least one cut extends from the inner-side surface toward the outer-side surface and penetrates the object-side mechanical surface and the image-side mechanical surface. The inner-side surface surrounds the optical axis and forms a through hole. A contour of the through hole has a shortest distance D1 passing through the optical axis and a longest distance D2 passing through the optical axis. The light-shielding element satisfies the following conditional expression: 1.200≤D2/D1≤3.000. An optical imaging lens is also provided.
