Abstract
A lens-fiber alignment housing for passively aligning an optical fiber with a lens, for improved alignment of a laser with the fiber, via the lens. The fiber is disposed in a substantially cylindrical, annular ferrule, the bottom end of which is disposed in the first end of a ferrule sleeve. The housing has an upper cylindrical mating section at a first end for mating with the second end of the ferrule sleeve, and a bottom lens-receiving section for securely receiving and mounting a lens. The lens may be mounted into the lens-receiving section of the housing, so that, when the housing is inserted into the second end of the ferrule sleeve, the lens and fiber are automatically, passively aligned, thereby forming an aligned lens-fiber assembly that can be aligned with the laser in a single active alignment procedure.
