Abstract

Fiber optical elements, in the form of a “field flattener,” a “distortion corrector,” and a “conical condenser” are combined in a single unit termed the “focon.” It is capable of correcting for field curvature and distortion of a lens system and because of the increase in photographic speed using conical fibers, the problem of other aberrations is minimized. Various features of a focon are discussed and it is shown that high performance optical systems are possible using simpler lens systems in conjunction with a focon.
