Abstract:
A collimator alignment system for assembling a fiber, a collimating lens, and a holder, the fiber having a first end and a second end and an optical axis, the holder having a longitudinal axis, the collimator alignment system comprising: a first fixture capable of holding the first end of the fiber in relation to the holder; a second fixture capable of holding the collimating lens relative to the holder; a stage on which at least one of the first fixture or the second fixture is mounted so as to be movable in a direction generally parallel with the optical axis of the fiber such that the displacement between the fiber and the collimating lens may be adjusted; a source emitting light into the second end of the fiber, the light being transmitted through the collimating lens; and a beam profiler including an optical detector receiving the light transmitted through the collimating lens for determining a beam size in at least one direction generally perpendicular to the optical axis of the fiber.
