A light beam source includes a laser diode having a housing. The housing has a base and a cap with an opening for emitting laser light. A lens mount having a generally tubular shape and being formed from a unitary piece of material is provided. The lens mount has a first end and a second end, the second end including inner walls. A lens is disposed at least partially within the first end of the lens mount, the lens being disposed so as to receive and focus the laser light as a beam. The cap of the laser diode is disposed at least partially within the second end of the lens mount and frictionally engages the inner walls. The inner walls include at least one longitudinal slot that allows the inner walls to expand and frictionally engage the cap when the cap is disposed in the second end of the lens mount.
