Vehicle-mounted ADAS wide-angle lens

The invention relates to the technical field of optical lenses, and in particular relates to a vehicle-mounted ADAS wide-angle lens, which is sequentially provided with a front lens group, a diaphragm and a rear lens group from an object space to an image space; the front lens group comprises a first lens, a second lens and a third lens, the rear lens group comprises a fourth lens, a fifth lens and a sixth lens which are all glass lenses, the first lens is a convex negative lens and a concave negative lens, the concave surface faces the image surface, at least one of the second lens to the sixth lens is a glass aspheric surface, and a group of glued lenses are arranged between the third lens to the sixth lens. The wide-angle lens is large in aperture, large in image plane size, high in illumination and small in distortion, and imaging of long-distance images is clear. 本发明涉及光学镜头技术领域，尤其涉及一种车载ADAS广角镜头，从物方到像方依次设有前透镜群组、光阑以及后透镜群组，所述前透镜群组包括第一透镜、第二透镜以及第三透镜，所述后透镜群组包括第四透镜、第五透镜以及第六透镜都为玻璃镜片，所述第一透镜为一凸一凹的负透镜，凹面向像面，且所述第二透镜到
