ABSTRACT:
A cylindrical glass blank (10) has one end received within a rotatable fixture (22) supporting the blank with its axis extending vertically. While rotating the fixture and glass blank at a given rate, a laser beam (54) is directed onto the upper blank end face (12) until the glass softens. The combination of the glass softening, glass surface tension and centrifugal force experienced from the rotation, the glass bank is formed into a convex lens (20).
