ABSTRACT:
An optical module includes a resin housing having an optical axis, a semiconductor device held in the resin housing in alignment with the optical axis, and a lens held in the resin housing in alignment with the optical axis. The resin housing includes a lens holder disposed in facing relation to the semiconductor device. The lens holder has a lens grip member disposed around the optical axis and projecting toward the semiconductor device. The lens grip member has a distal end projecting radially inwardly. The lens holder also has a lens seat at a proximal end of the lens grip member. The lens grip member and the lens seat are integrally molded with the resin housing. The lens is held by the lens seat and gripped by the lens grip member after the lens is forced past the lens grip member toward the lens seat. The lens grip member comprises three lens grip fingers circumferentially spaced at equal angular intervals.
