Abstract

A Reid surface-grinder, available in many university shops has been economically modified for the fabrication of cylindrical surfaces, either convex or concave, with radii of curvature in the 5 to 10 meter range (0.4 to 0.2 diopter). The generation of larger radii of curvature requires only a slight modification of the current apparatus.
