Optical scanning apparatus and its optical element, method and apparatus for positioning and fixing the optical element, and a molding tool for making the optical element |
摘要 |
Method and apparatus for optical scanning includes a sliding bed and a center adjusting unit. The sliding bed predetermines a position of an optical element in a light axis direction. The optical element has at least one lens surface to be have been subjected to a precision-figure transferring and optically scanning at least one light beam generated by a plurality of light sources and deflected by a rotary mirror. The center adjusting unit moves the optical element to make a lateral center of a curvature radius of the optical element exactly on a light axis center. This paper also describes an optical element itself, a method and apparatus for positioning and fixing the optical element. This paper further describes a molding tool for making the optical element.
