Product Focus April 2019: Laser Machining/Marking

Custom Ball Lens

Laser Components, Bedford, NH, provides custom ball lens profiles on the end faces of silica fibers. The plasma-based CMS process with ring-of-fire technology supports fiber diameters of 200, 365, 400, 550, and 600 m, including other diameters within the limits of the equipment. For fibers used in medical applications, end-face processing can be carried out in a cleanroom in accordance with ISO 13485. The entire process is also compliant to ISO 13485 hygiene requirements. The rounded surface of the ball lens reduces the risk of injury during the operation whilst at the same time controlling the beam characteristics of the laser. The same type of fiber tips is also used in other applications for coupling light sources with the fiber.
