An optical collimator (10) for collimating light beams coming from an optical fiber (13) includes the at least one optical fiber, a ferrule (12), a molded lens (11), a mounting tube (14) and a metal holder (15). The optical fiber has an exposed end and the ferrule defines a through hole for receiving and fixing the optical fiber therein. A forward face (122) of the ferrule is ground at an oblique angle and is flush with the exposed end of the optical fiber. The molded lens is cylindrical in shape and has an oblique surface coinciding with that of the ferrule and the exposed end of the optical fiber. The molded lens has a convex surface at its forward face (111).
