Abstract

613,614. Optical systems. PERKIN-ELMER CORPORATION. June 19, 1946, No. 18463. Convention date, June 19,-1945. [Class 97 (i)] An optical system for cameras, projectors, &c comprises a spherical concave reflector, a pair of spherical shells of substantially uniform thickness and substan. tially concentric with the reflector and lying on opposite sides of the centre of curvature thereof with their concave surfaces opposed and an aspheric correcting plate lying between the shells and figured to correct for the residual spherical aberration of the combination of the reflector and shells. The embodiments described are the same as those described in Specification 613,608 with the addition of the system shown in Fig. 6 comprising reflector 26, shells 27, 28 and plate 29 and which is for use as a camera objective. Numerical data are given.
