The present invention is an imaging module (10) including a frame (12) supporting various optical components and a circuit board (14), which, in one embodiment, carries essentially an entirety of illumination (16) and aiming (18) LEDs of the module. The frame may include resilient fingers (48) which enable the frame to receive certain optical components in a snap-fit arrangement. Further, the module may be arranged so that the outer walls (31) and (31') of the module provide a containment for preventing structural damage to sensitive and fragile internal components of the module.
