Abstract

871,488. Lens mount. AGFA A. G. March 1, 1960 [March 3, 1959], No. 7280/60. Class 97(1) A magnifying lens has one or more lens components, e.g. 1, 2, in a mount a transparent portion 5 of which spaces the lenses from the subject to be viewed and converges light passing through it on to the field of view. In the Fig. surfaces 6, 7 provide the convergent effect but these surfaces could be replaced by a spherically or cylindrically lenticulated surface. An opaque ring 8 serves to delineate the eye aperture.
