Abstract
A lens of a soft and readily damaged material is placed onto a support having a surface whose contour corresponds to the mating contour of the juxtaposed surface of the lens. The support is rotated and the lens is shifted on it until the lens is centered on the surface of the support, whereupon suction is applied through the support to the lens to hold it immovable as the marginal zones of the lens are being worked.
