ABSTRACT:
An assembly for collecting light from indicia includes a chassis having a port through which the light from the indicia passes, and walls bounding an interior compartment. A self-retaining frame constituted of an optical material is non-adhesively mounted within the compartment in an assembled position. The frame has an integral lens optically aligned with the port in the assembled position for optically modifying the light passing through the port, and a plurality of legs in gripping frictional interference engagement with the walls in the assembled position. A sensor is optically aligned with the lens, for sensing the light optically modified by the lens.
