Expanded beam fiber optic lens

A lens for an optical fiber is formed on the end of a capillary glass tube which is then fitted over an optical fiber. The lens can be formed by mounting a capillary tube in a spindle, and rotating and heating the end of the tube until centrifugal force forms the lens as a bulbous portion.
