Abstract
In this invention, the depth of lapping an optical flat on optic fibers is monitored while the fiber is mounted on the lapping fixture. A collimated light beam is tangentially incident upon the optical flat. A portion of the incident light is transmitted into the optic fiber. A light intensity monitor coupled to the end of the optic fiber measures the amount of transmitted light relative to a standard value. The amount of light transmitted is a function of the surface area of the optical flat. A monitor measurement of a predetermined intensity level indicates sufficient material has been removed from the optical fiber.
