Abstract
The present invention relates to a method for enabling reliable, consistent alignment of a beam of light eating the end of an optical fiber, which has been cut at a non-perpendicular angle, with a collimating lens. The method involves utilizing a spherical shape to generate two bores in the object which intersect the center at a predetermined angle. The predetermined angle is equivalent to the angle of the light beam exiting the end of the optical fiber.
