Abstract
Method and Apparatus for Forming a Lens on an Optical Fiber includes a fiber rotator assembly that receives and axially rotates an optical fiber. The optical fiber is positioned through a fiber support assembly that includes an air bearing for the near frictionless rotation of the fiber. A fiber forming assembly is positioned adjacent the end of the optical fiber and includes an abrasive disc mounted to the shaft of an abrasive disc motor. The fiber forming assembly is advanced toward the rotating optical fiber for the rotating abrasive disc to contact and remove a portion of the tip of the fiber forming a cone having a predetermined cone angle. A fiber profiling tool having a flexible abrasive flap is advanced to contact the cone-shaped tip of the rotating fiber to remove a portion of the cone to form a lens on the end of the fiber.
