  • Zoom lens and magnifier utilizing the same
    Patent number: 5703727
    Abstract: A zoom lens is described which is quite simple and yet provides a wide (5:1) zoom range. The lens consists of a front focusing negative lens which provides a stationary virtual image for two rear zooming lens groups. These two zooming groups are positive and reimage the object at a camera pickup device. Such zooming groups are of substantially equal focal length and bear equally in the magnification change. The invention includes a magnifier which utilizes the zoom lens and has the mechanical aspects necessary to provide the needed lens motions.
