[0002] A wide-angle lens is a lens that can capture a wider viewing angle. It is divided into two types: ordinary wide-angle lens and ultra-wide-angle lens. The focal length of an ordinary wide-angle lens is generally 38-24 mm, and the viewing angle is 60-84 degrees; the focal length of an ultra-wide-angle lens is 20-13 mm, and the viewing angle is 94-118 degrees. Since the wide-angle lens has a short focal length and a large viewing angle, it can capture a larger area of ​​scenery within a shorter shooting distance. Based on this characteristic, it is usually widely used in surveillance or vehicle-mounted camera devices.
