Abstract

427,008. Lenses. LEE, H. W., and KAPELLA, Ltd., 104, Stoughton Street, Leicester. Dec. 21, 1934, No. 36634. Addition to 377,537. [Class 97 (i)] The parent Specification describes a lens system comprising two separate components each consisting of a single collective element and a compound dispersive member consisting of a collective element in contact with a dispersive element. According to this invention the elements of each of the said compound dispersive members are arranged to have between them an air space in the shape of a collective meniscus lens, the said elements being in contact around their peripheries. Data are given.
