Abstract

1, 008, 952. Reflecting objectives. EDNALITE CORPORATION. Nov. 5, 1963 [Feb 25, 1963], No. 43697/63. Heading G2J. A lens system, equivalent to a symmetrical six-element lens system, comprises a double, sing- let and a plane mirror, the difference between the refractive indices of the components of the doublet lying between 0.060 and 0.074 measured at the standard sodium D line. Optical data are given for the example shown.
