Abstract

4366. Aitchison, J. March 2. Telescopes.-In object glasses for telescopes, binoculars, and like glasses, the ratio of aperture to focal length is increased by the use of combinations of two or more lenses of larger diameter than is usual mounted near together. Such a combination of the lenses c with an intermediate air space d is shown in Fig. 3. It is stated that, by proper selection and arrangement of lenses, spherical and chromatic aberrations may be more perfectly corrected. The curves, axial thicknesses, and optical constants of the component lenses of one system are given in the Specification.
