Abstract
An optical collimator (10) includes an input optical fiber (11), an output optical fiber (12), a ferrule (13) receiving the input optical fiber and the output optical fiber therein, a molding lens (14), and a filter (15). The molding lens includes a solid cylindrical main body (141), and a pair of cylindrical protrusions (142, 143) respectively extending from opposite ends of the main body. The main body includes an inmost oblique end face (18), and an opposite aspherical end face (19). The ferrule is received in one protrusion and opposes the oblique end face. The filter is received in the other protrusion and opposes the aspherical end face.
