A scan engine ( 15 ) includes illumination sources ( 48, 50 ) for projecting a light beam ( 40 ) upon a target object, a focusing lens ( 44 ) that receives a reflected light ( 34 ) of the target object and focuses a reflected image ( 35 ) as it passes through the focusing lens ( 44 ) along an optical axis (A-A), and a linear sensor ( 46 ) that receives the reflected image ( 35 ) from the focusing lens ( 44 ). The linear sensor ( 46 ) provides a signal ( 59 ) representing the reflected image ( 34 ). A circuit board ( 16 ) is integrally connected to the illumination sources ( 48, 50 ) and the linear sensor ( 46 ).
