Paper Abstract

This paper reports on a novel plastic-molded total-reflection type polygonal laser beam deflector. The present deflector is fabricated by the optical resin molding which is suitable for low cost mass production, because expensive and time consuming aluminum reflection film deposition process has been eliminated. A bar-code reader that employs the present laser beam deflector shows readout performance comparable to that of a bar-code reader that employs the conventional aluminum deflector. The condition of no deterioration of the field depth of the resolving power for the bar-code is that, waviness on a deflector surface Wmax is to be less than 10 nm.
