Abstract
An optical collimator ( ) includes an optical fiber ( ), a metal ferrule ( ), a Graded Index (GRIN) lens ( ) and an outer metal tube ( ). The optical fiber has an exposed end ( ) which is coated with metal. The exposed end of the optical fiber is inserted into the ferrule and laser welded thereto. The GRIN lens is also coated with metal. A plurality of soldering holes ( ) is defined in a periphery of the outer tube. Solder is applied to the ferrule and the GRIN lens through the holes to firmly connect the outer tube, the ferrule and the GRIN lens together. After assembly, if the position of the GRIN lens or the optical fiber is found to be inaccurate, the GRIN lens and the ferrule can be easily resoldered.
