摘要： An optical pickup lens device includes, in the order from the light source side, a collimating lens for converting a bundle of rays into parallel rays or predetermined convergent or divergent rays, the collimating lens being movably held along a direction of an optical axis of a bundle of rays emitted from a light source; an aberration correcting element for allowing a bundle of rays emitted from the collimating lens to be transmitted therethrough; and an objective lens element having a numerical aperture of 0.8 or more, and converging a bundle of rays coming from the aberration correcting element onto the information recording medium to form a spot. The aberration correcting element and the objective lens element are integrally held together in a direction orthogonal to the optical axis so as to perform tracking on the information recording medium, and satisfy predetermined conditions.

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： A low-cost contact detection sensor and contact detection method for easily detecting a contact by a third party is provided. A contact detection sensor comprises an antireflection structure including structure elements having a predetermined shape which are put in an array periodically at a pitch smaller than a wavelength of visible spectrum; and a substrate including the antireflection structure in at least a part of a surface portion thereof. The antireflection structure distinguishes whether the detection target is contacted by a human body or not based on a change in reflectance which occurs to an area of the detection target contacted by the human body when the detection target is contacted by the human body.
