Abstract

This paper proposes a physical model of the transmission of a pencil of rays propagating along the optic axes through the concave surface of a convexo-concave lens made from strained synthetic sapphire and shows that it is possible to vary the focal length of the lens while keeping the focus of the optic axes constant.
