摘要： An imaging system includes incidence faces composed of optical faces having an image focusing function; prisms; and exit faces. The incidence faces are arranged with a first pitch along a first axial direction. The prisms are arranged with a second pitch along the first axial direction. The exit faces are arranged with a third pitch along the first axial direction. The first axial direction is set as a Y direction. A normal line direction of a face top of an optical face of the incidence face in a plane perpendicular to the first axial direction is set as a X direction. A direction perpendicular to the Y direction and the X direction is set as a Z direction. In a XZ cross-section plane, a width of the prism in the Z direction is smaller than a width of optical face of the incidence face in the Z direction.

摘要： An aperture has an aperture opening that transmits a predetermined portion of a light beam. A phase optical element changes a phase of a portion of a light beam. A scanning lens focuses the light beam into a beam spot on a scanning surface. The phase optical element has a function of increasing light intensity of a side-lobe of the scanning beam near the scanning surface. The aperture opening is set to satisfy 0.03≦(SR−SA)/SR≦0.20, where SR and SA are areas of a rectangle circumscribing the aperture opening and the aperture opening, respectively. The function of the phase optical element and the aperture expand a depth allowance of the beam spot.
