Abstract

1335514 Annular field corrected lens PERKIN-ELMER CORP 21 June 1972 [21 June 1971] 29139/72 Heading G2J At least two optical elements are combined in a coaxial relationship and optically corrected to produce an optically corrected annular field which is utilised by screening off the rest of the lens field. Two spaced slits may be formed in the screen to give stereoscopic images.
