Abstract
A pre-scan optics assembly for a laser scanning device. A housing includes reference surfaces against which a pre-scan lens is directly referenced, to restrain the lens against rotation about the optical axis and the scan axis of the device. A lens carrier is attached to the housing and has an abutment surface to restrain the lens against rotation about the process axis of the device. A spring clip secures position of all components in the desired locations. The optical system aperture is formed directly in a wall of the lens carrier.
