Abstract

See full text

An imaging lens including an aperture and a lens with refractive power arranged from a zoom-in side to a zoom-out side along an optical axis is provided. The aperture includes a substrate and a light-shielding layer. The substrate includes a first middle region and a first outer edge region surrounding the first middle region. The first outer edge region allows visible light and infrared light to substantially pass therethrough. The light-shielding layer includes a second middle region and a second outer edge region surrounding the second middle region. The second outer edge region allows infrared light to substantially pass therethrough and substantially shields visible light. A thickness of the aperture is between 0.01 mm and 0.3 mm along a direction of an optical axis. Furthermore, an imaging lens and a manufacturing method of a light-shielding element are also provided.
