    Abstract: A light source unit, which is employed in an optical head for an optical disc drive, is provided with a laser diode having a plurality of light emitting points. The plurality of light emitting points are spaced from each other by a predetermined minute amount. One of a plurality of laser beams having different wavelengths is selectively emitted from the plurality of light emitting points. The light source unit further includes a collimating lens that collimates each of the plurality of laser beams respectively emitted from the plurality of light emitting points. The plurality of laser beams passed through the collimating lens proceeds in different directions. The light source unit further includes a transparent optical path compensation element having a predetermined dispersion characteristic. Each of the plurality of laser beams emerging from the collimating lens is emerged from the transparent optical path compensation element along the same optical path.

    Abstract: There is provided an optical system for an optical disc which requires a numerical aperture larger than or equal to 0.60. The optical system is provided with a light source, an objective lens, and a driving system that controls a position and an attitude of the objective lens. The driving system operates to move the objective lens in a direction perpendicular to a central axis of the objective lens for a tracking operation, and to change the attitude of the objective lens during the tracking operation so that the central axis on a light source side tilts toward the light source.

    Abstract: When bonding a workpiece to a substrate, processed parts of the substrate and the workpiece are observed and behavior such as the production of voids and the flowing of resin is observed. An apparatus for observing an assembled state of components includes: a stage on which a substrate is set; a head mechanism that bonds, by applying heat and pressure, an observation workpiece made of a transparent material to the substrate via resin supplied between the substrate and the observation workpiece; a light source that irradiates an observed part of the substrate and the observation workpiece mounted on the stage with light; and a camera that takes, from the observation workpiece side, an image of the observed part when the observation workpiece is bonded to the substrate set on the stage.
