A lens module ( 8 ) includes a housing ( 10 ) and a plurality of lenses ( 21, 22, and 23 ). The lenses are received in the housing. Each lens has a protrusion ( 213, 223, and 233 ) and a hole ( 214, 224, and 234 ). The protrusion of a given lens is received in the corresponding hole of an adjacent lens, thereby integrating (i.e., mechanically coupling) the lenses together. Therefore, all the lenses are arranged coaxially.
