A method for producing a ball lens including determining a feed length of optical fiber based on a target ball lens diameter; providing heat energy to a heating zone; moving, at a predetermined speed, one of the optical fiber and the heating zone so that the end of the optical enters the heating zone to heat the end of the optical fiber; and stopping the heating of the end of the optical fiber when the amount of moving the one of the optical fiber and the heating zone equals the determined feed length.
