    摘要： A spread lens including a first lens surface through which the emitted light from the light emitting device is inputted; a second lens surface spreading the inputted light to an outside; refraction parts which extend between both side ends of each of the first and second lens surfaces, are formed in a concave-convex shape, and refract the emitted light from the light emitting device; and support parts which extend at both side ends of the second lens surface and separate the refraction parts and the light emitting device from each other.

    摘要： When it is intended to realize a lens having a large NA with one lens, an adjustment precision between both surfaces of the lens is very strict. Accordingly an objective lens having an NA of 0.8 or more was usually realized by two lenses. However, a working distance is small, and collision of the objective lens with a disc is apt to occur. A coma corrector for compensating coma caused by decentering of both surfaces in realizing the high NA lens with one lens is added. However, in this case, astigmatism occurs when the objective lens decenters from the coma corrector relatively accompanied with a tracking operation. The objective lens and the coma corrector are fixed to a mirror barrel so as to be unified with each other, and driven by a two-dimensional lens actuator. With such a constitution, decentering of the objective lens and the coma corrector does not occur, and hence astigmatism does not occur.

    摘要： A lighting fixture includes: a base; a plurality of optical sources attached on an upper surface of the base to emit light; a heat spreader attached to the base to radiate heat emitted from the plurality of optical sources; and a light diffusion lens disposed on the upper surface of the plurality of optical sources to refract light emitted from the plurality of optical sources and to increase an irradiation angle of light. In the lighting fixture, an irradiation angle of light emitted from an optical source is close to that of a general electric-light bulb and thus a light distribution characteristic of the lighting fixture may be improved.

    摘要： When reproducing a multilayer optical disk using a high-numerical-aperture objective, the period of time required before the disk is reproduced is reduced by discriminating recording layers. A spherical aberration signal is detected as a differential signal between focus position fluctuation signals respectively in a central section and in a peripheral section of a reproduced flux of light. A recording layer is discriminated using a quantity of correction of spherical aberration at a zero-crossing point of a level or a spherical aberration signal associated with the differential signal. After adding the spherical aberration for the correction of the discriminated layer, residual spherical aberration is corrected by feedback control using a residual spherical aberration signal.
