Patent number: 6937381Abstract: An optical pickup device which includes (A) a light source, and (B) an objective lens and an aberration correcting optical system which are located in a light path from the light source to an optical recording medium is so arranged that the aberration correcting optical system imparts a phase distribution to luminous flux which transmits the aberration correcting optical system, so as to correct a predetermined aberration; and an amount of phase of the aberration correcting optical system when correcting the aberration is set in such a manner that the aberration correcting optical system imparts a larger amount of phase at a position farther from a point where the aberration correcting optical system crosses an optical axis of light emitted from the light source. With this, it is possible to increase a tolerance for the center misalignment of the objective lens so as to reduce aberration caused by the center misalignment.Type: GrantFiled: August 13, 2002Date of Patent: August 30, 2005Assignee: Sharp Kabushiki KaishaInventors: Kazuya Kitamura, Yukio Kurata, Tetsuo Iwaki

Patent number: 6822799Abstract: An exposing apparatus for a microlens array allows for easy alignment and attains high accuracy. An exposing method for a microlens array attains high accuracy and high light efficiency. The exposing apparatus for a microlens array includes a micro fly-eye lens for converting a light beam from a light source into a secondary point light source, a transmittance distribution mask for adjusting the luminance of the light of the secondary point light source, and a collimator lens for converting the light of adjusted luminance into a parallel light beam and for guiding the parallel light beam, via a first microlens array which is formed in advance, to a photosensitive resin layer to be a second microlens array. The light emitted from the light source is transmitted through the micro fly-eye lens, the transmittance distribution mask, and the collimator lens. The light is then adjusted to a desired luminance to expose the photosensitive resin of a microlens substrate.Type: GrantFiled: August 27, 2003Date of Patent: November 23, 2004Assignee: Sharp Kabushiki KaishaInventors: Kazuya Kitamura, Kuniaki Okada, Yoshihiro Sekimoto, Yukio Kurata, Hiroshi Nakanishi
