An optical fibre collimator 300 and method of fabrication. The collimator has a housing 310 with a through-hole or cavity 305. The through-hole has a longitudinal axis, a first longitudinal portion 305a having a first internal diameter and a second longitudinal portion 305b having a second internal diameter. The collimator has a lens 303 moulded directly into the second portion, where the first portion is arranged to receive an optical fibre ferrule. The first internal diameter may be greater than the second internal diameter and the first and second portions may be connected by a shoulder 307. The method of fabrication involves boring a first hole forming a first portion in a housing, machining a second hole forming a second portion in a housing, inserting a moulding tool into the first portion and directly moulding a lens into the second portion. |
