Abstract

A detector assembly for use in an optical reader comprises a hollow housing in which is mounted on the central axis of the housing a collection lens, a routing mirror, a light filter and a photodetector. A routing lens mounted in the side of the housing and on an axis which is perpendicular to the central axis of the housing directs the scanning light at the routing mirror which in turn reflects the light in a scanning direction.
