摘要： A beam splitting element includes a transparent substrate and a diffractive grating formed on the substrate for dividing an incident beam into a plurality of diffracted beams. The diffractive grating has a plurality of identically formed belt-shaped phase patterns that are arranged in parallel lines at equal pitches. The phase pattern has a sectional shape in a plane perpendicular to the parallel lines that causes non-linear phase difference to the beam passing therethrough within one pitch. Further, the adjacent phase patterns are connected without phase gaps at the boundaries therebetween.

摘要： Disclosed is a multi-beam optical system that includes a laser source, a diffractive beam dividing element that divides the light beam emitted from the laser source into a plurality of light beams, a propagation optical system through which the divided light beams propagate, a polygon mirror and a scan lens. The propagation optical system includes a curved surface mirror that is arranged such that center axes of the reflected light beams are spatially separated from center axes of the incident light beams at a predetermined separation angle. The diffractive beam-dividing element Is arranged such that the center axis of the incident light beam is inclined with respect to the normal to a diffraction grating surface thereof so as to compensate bending of a beam spot line, along which the beam spots align, depending on the separation angle of the curved surface mirror.
