摘要:
A mirror includes a substrate, a reflection layer, and a protection layer. The substrate includes a surface having an attachment area and a reflection area. The reflection layer is formed on the reflection area. The protection layer is formed on the reflection area on which the reflection layer is formed and the attachment area. Material of the protection layer is homogeneous across the reflection area and the attachment area.

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.
