摘要

The system (2) has a wide-angle objective (4) having several lenses and a transparent protective plane plate located before the wide-angle objective. The plane plate is a parallel surfaced plate. The plate is a glass plate. The wide-angle objective lens system has an objective for the collection of light from an incoming object from a diagonal angle field of 120 deg plus-minus 10deg. The wide-angle objective lens system has a switched optical aperture (8). A second wide-angle objective lens system (6) projects on an image area (10) with a distortion of less than 3 percent. An independent claim is included for a wide-angle objective lens system, and a wide-angle camera for the supervision of the immediate environment of motor vehicles.
