Abstract

127,058. Taylor, A., and Taylor, H. D. April 19, 1917. Lenses.-A triple combination lens for photographic or telescope objectives comprises a double convex positive lens of low refractive index enclosed between and optically united to, or cemented to, two meniscus negative lenses of very high refractive index and approximately equal power. Two such lenses placed close together may be used to form a photographic objective of aperture substantially one-half to one-third of the equivalent focal length. Such a combination is shown in the Figure, together with a negative correcting system for obtaining a flat image and placed in or almost in the plane of the image produced by the two lenses. Optical data are given in the Specification.
