Abstract:
A method for enabling reliable, consistent alignment of a beam of light exiting an end of an optical fiber, with a collimating lens, wherein the optical fiber end is cut at a non-perpendicular angle to a longitudinal axis of the optical fiber, and the beam of light exits the optical fiber end at an exit angle relative to the longitudinal axis, said method comprising the steps of:providing an object comprising a spherical surface having a center; generating a first bore in said object, said first bore having a longitudinal axis intersecting said center; generating a second bore in said object, said second bore having a longitudinal axis intersecting said center, said longitudinal axis of said first bore and said longitudinal axis of said second bore intersecting said center at a predetermined angle, said predetermined angle being equivalent to the exit angle and being determined by the non-perpendicular optical fiber cut angle; positioning the end of the optical fiber in said first bore; and positioning the collimating lens in said second bore, whereby the beam of light is aligned substantially with the center of said collimating lens.
