Abstract: A phase shift element having a central area (for transmitting part of an incident laser beam in the vicinity of the beam central axis) and a first area (giving the laser beam incident thereon a phase difference null relative to a beam passing through the central area) is placed on an optical path between a laser light source and a polygon mirror of a scanning optical system. The scanning optical system including such a phase shift element is installed in a printer. By the effect of the phase shift element, the intensity of side lobes (several rings of light accompanying the main beam) is prevented from exceeding a threshold value even when optical surfaces of an imaging optical system of the scanning optical system have certain microscopic undulations, by which black stripes occurring in halftone printing can be eliminated.

Abstract: An anti-reflection spectacle lens has an anti-reflection film composed of a plurality of layers formed on at least one surface of a lens substrate or other one or more layers formed on said lens substrate, the anti-reflection film comprising an outermost layer made of silicon oxide, on which a water- and oil-repellent layer is formed by vacuum deposition. The spectacle lens is excellent in water and oil repellency, and aqueous stains and oily stains attached to the spectacle lens can easily be wiped off. The use of a pellet impregnated with a hydrophobic, reactive organic compound in a vacuum deposition chamber contributes to the reduction of a production cost.
