Abstract

521,158. Prisms. ZEISS IKON AKT.-GES. Nov. 9, 1938, No. 32550. Convention date, Nov. 12, 1937. [Class 97 (i)] [Also in Group XL] An annular prism 1, Fig. 2, or a pair of straight prisms (Figs. 4, 5, not shown) is used to direct only light coming from a narrow angle by double total reflection on to a light-sensitive cell 2. Specification 479,041, [Group XL], is referred to.
