Abstract

A scanning optical system employing plastic lenses was studied in order to realize a high resolution laser scanning optical system with simple construction. A simulation program was developed to analyze the effect of lens surface error which was a problem with plastic lenses. As a result we confirmed suitable lens disposition which would make possible a high resolution optical scanning system when employing current high precision plastic lens production engineering. Including this result, compensation of focus shift and correction of aberration were studied. Consequently, the optical scanning system with simple construction was designed, and a small and uniform scanning spot was achieved in our prototype of the optical system.
