  • Patent number: 5559640
    Abstract: An automotive rear view mirror system comprises passive optical elements (which may include lenses, but must include one or an odd number of mirrors) configured to provide a wide field of view with a negative optical element having a small width dimension mounted externally and close to the body of the vehicle. In a basic embodiment, a small negative optical element, such as a convex mirror, is mounted outside the vehicle, and a larger positive optical element, such as a convex lens, is placed inside the vehicle. The optical elements are positioned to be substantially confocal, with the distance between them equal to the difference in their focal lengths, so as to cancel the curvature of field generated by the external element. The internal element magnifies the image to a size comparable to that obtained with a standard external flat mirror.
