SOLUTION: The reflection preventive films are formed on the surface part 1a and a rear surface part 1b of a lens 1 consisting of nitric material and transparent synthetic resin material. The film thickness are different from each other among the reflection preventive film formed on an incident first area A1 being the area of the central part of the surface part 1a, the reflection preventive film formed on an incident surface second area B1 being the circular area of the peripheral part of this incident surface first area A1 and the reflection preventive film formed on an incident surface third area C1 being the circular area ranging from the outer edge of this incident surface second area B1 to the peripheral part of the lens surface. Further, related to the rear surface part 1b also, the film thickness are different from each other. The differences in the film thickness in every area of these reflection preventive films are decided according to the incident angle (outgoing angle) shown by θ of the luminous flux for the lens surface in the area.

Abstract: PROBLEM TO BE SOLVED: To accurately attach a multilens for an optical pickup made of glass to a lens holder and to reduce a manufacturing cost of the multilens. SOLUTION: Planes parallel to an optical axis X-X of the multilens 1 for the optical pickup made of glass form two planes (a first reference flank 4 and a second reference flank 5) which are respectively parallel to or orthogonally intersecting with a cylindrical generatrix 6 of a cylindrical surface 2 being a front surface of the lens. On one surface of a planar glass preform material, projecting lines 16 having cylindrical surfaces and stretching in cylindrical generatrix directions are formed by pressing. On another surface at a part opposed to the projecting line 16, plural spherical recessed parts 17 having recessed spherical surfaces are formed along the cylindrical generatrix directions and then respective spherical recessed parts are cut as a unit.

Abstract: PROBLEM TO BE SOLVED: To improve productivity, to reduce production costs and to improve reliability in a focusing error signal and a tracking error signal. SOLUTION: In an optical disk device 1, a beam emitted from a light source 31 is split to three of main and side beams by a first diffraction grating 45 in an optical pickup 3, an optical disk 2 is irradiated with the beams by an objective lens 34, +1st-order light is used as return light by diffracting the optical path of respective return beams from the optical disk 2 by a second diffraction grating 46, and -1st-order light is used as return light by diffracting the respective return beams diffracted by the second diffraction grating 46 by a third diffraction grating 46. Therefore, the fluctuation of the optical path in the second diffraction grating 46 is corrected by the wavelength fluctuation of light emitted from the light source 31 and the return beams diffracted by the third diffraction grating 47 are each split to a plurality of beams by a splitting prism 48. Besides, the main beams split by the splitting prism 48 are each received by a light receiving part 35. Therefore, a focusing error FE is acquired and the side beams transmitted through the splitting prism 48 are received so that the tracking error signal can be acquired.
