摘要： A solid-state imaging device includes pixels 2 arranged two-dimensionally on a semiconductor substrate 1. In a predetermined area in each pixel is formed a light-sensitive area 3 for receiving incident light 11, and each pixel includes a photoelectric conversion portion 4 for converting the incident light into a signal charge. In at least some of the pixels, the center of the light-sensitive area is offset from the center of the pixel when seen from directly above a principal surface of the semiconductor substrate. Each pixel further includes a light-path change member 12a and 12b for deflecting incident light traveling toward the center of the pixel so as to be directed toward the center of the light-sensitive area. Thus, a solid-state imaging device simultaneously realizing the miniaturization of pixels and a high image quality is provided.

摘要： In a lens array, a multiplicity of condenser lenses, each in a convex lens form, are arrayed in vertical and horizontal directions so as to correspond to pixel regions, respectively, and each condenser lens, when viewed from a direction perpendicular to a condenser lens-arrayed plane, takes a planar shape formed with a four straight sides along four sides of the pixel region and four circular arcs extending between the respective straight sides. A center of the four circular arcs substantially coincides with a center of the corresponding pixel region. This ensures an increase in area covered with the condenser lens in the pixel region, thereby causing more light rays to enter the condenser lens. In addition, a radius of curvature necessary for collecting can be obtained more easily. Consequently, light rays can be efficiently collected and guided to light receiving sections or the like provided in the pixel regions. Accordingly, sensitivity is improved when such a lens array is used in a solid-state imaging element, while luminance of a screen is improved when it is used in a panel display element. Besides, such a lens array is easily manufactured.

摘要： Coma of an objective lens occurs depending on the lens-forming condition when plural disks of different substrate thickness are recorded and reproduced. An objective lens according to this invention is not influenced by the coma even if the thickness of the substrates is changed. For this purpose, a diffraction grating whose aberration is corrected is formed on the first side of an aspheric objective lens. Due to this correction, light beams having different diffraction orders, e.g. 0th order diffracted light and +1st order diffracted light, are focused respectively on two kinds of substrates of different thickness. The whole objective lens is tilted to correct its axial coma, and the tilt angle is predetermined to be substantially identical with respect to plural substrates which are different in thickness.

摘要： A light quantity distribution control element includes a substrate of 20 mm×20 mm×3 mm made of a material that transmits light, such as optical glass or acryl, and a antireflective structure provided on a surface of the substrate. As the antireflective structure, a conical antireflective structure of a pitch of 0.15 μm (periodic structure having conical convexities) is formed. This corresponds to a antireflective structure having a pitch of a wavelength or less in the ultraviolet band (150 nm to 400 nm) at the time when ultraviolet light is used as incident light.

摘要： A cylinder-shaped Cr mask having a diameter of 0.15 μm is formed at a pitch of 0.15 μm on a quartz glass substrate. The quartz glass substrate on which the cylinder-shaped Cr mask is formed is placed in a RF dry-etching apparatus and the surface of the quartz glass substrate is etched with CHF3+O2 gas. Thus, a cone-shaped antireflection structure with a pitch of 0.15 μm and a height of 0.15 μm is formed on the surface of the quartz glass substrate. An Ir—Rh alloy film having a thickness of 0.05 μm for protecting the surface is formed on the surface (pressing surface) of the quartz glass substrate provided with the cone-shaped antireflection structure to form a mold having an antireflection structure. An optical material 11 (crown based borosilicate glass) to which a releasing agent containing carbon (C) particulates for mold release is applied is press-molded with the mold having an antireflection structure, and the press-molded optical material is released from the mold having an antireflection structure without cooling. After the press-molded optical material is cooled, the releasing agent is removed.

摘要： An optical system for an optical disk, comprising a light source (61), a collimating optical system (63) for converting a luminous flux from the light source into parallel rays of light, and an object lens (66) for condensing the parallel rays onto the information recording surface (71) of an optical disk. The object lens consisting of two or three lenses and having a numerical aperture (NA) of at least 0.82 enables a high-density recording. Since a third-order astigmatism produced when the object lens is tilted 0.7 degree with respect to an optical axis is as small as up to 10 m lambda, a residual aberration, after a third-order comatic aberration produced when the optical disk is tilted due to warping or the like is corrected by tilting the optical lens, can be reduced. Therefore, a tilted optical disk still can ensure a satisfactory recording and/or reproducing quality.
