Abstract

220,266. Atha & Co., J. W., (Albada, L. E. W. van). June 5, 1924. Lenses.-The optical system of a magnifying glass consists of a front 'dispersive member and a rear collective member, which may be a simple or a compound lens. The members of the system are spaced apart, the space between them comprising a collective air-lens. The back surfaces of each member may be plane. Numerical data are given in the Specification.
