  • Patent number: 4750810
    Abstract: Lenses (10,11) , e.g. for a camera for a video conferencing system, have divergent optical axes and focus real images via prisms (20,21,22,23) on to a focal plane f. A prism (20) in one path introduces an additional reflection to invert the image while that (22) in the other path causes lateral inversion, so that the two images do not suffer either type of inversion relative to one another. The final reflecting surfaces 211,231 abut in the plane f so that the real images are closely juxtaposed.
