Abstract
Imaging arrangements and barcode readers including such imaging arrangements. An imaging arrangement for use in a barcode reader includes a housing. The imaging arrangement also includes a light source configured to emit light along a central light axis. The light source is disposed in the housing. The imaging arrangement also includes a lens having a first surface and a second surface opposite the first surface. The lens is disposed in the housing. The first surface is configured to face the light source and is structured to substantially collimate light received from the light source into a collimated beam. The second surface includes surface structures structured to generate a patterned beam in response to receiving the collimated beam.
