摘要: An optical scanner unit has a window which transmits light from inside the to target, for example, bar code, and receives target into scanner. The is tilted at Brewster's angle permit exit without "exit reflection" of off interior window. also permits returned scanned enter be sensed by photodetector therein. same may used transmitted source. disposed relative scanning beam center scan, close over entire scan.
