The apparatus (10) includes a batch wafer presentation system (12) receiving a cassette (14) carrying a plurality of wafers (16). The batch wafer presentation system (12) arranges the plurality of wafers (16) along an inclined presentation axis, .alpha., to simultaneously expose the bar code inscription on each wafer (16). A laser scanner (30) is mounted on an arm assembly (32) which travels long a track (34) parallel with the presentation axis. The laser scanner (30) is mounted such that its angular and spatial positions relative to the plurality of wafers (16) may be easily adjusted.
