摘要： Photo-masks for fabricating surface-relief grating diffractive devices and methods of fabricating surface-relief grating diffractive devices are described. The photo-mask can include refractive elements and/or diffractive elements contained in or on a body element. The photo-mask can be used to simultaneously produce multiple surface-relief grating diffractive devices in a recording material. The photo-mask enables the surface-relief grating diffractive devices to be produced in large quantities while significantly reducing the cost and labor required.

摘要： An optical pickup apparatus according to the present invention includes: a first light source for emitting a first light flux; a second light source for emitting a second light flux; a third light source for emitting a third light flux; and an objective optical element. The objective optical element has an optical surface including at least two areas provided with optical path difference providing structures. The objective optical element converges the first to third light fluxes each passing through the predetermined areas on the objective optical element onto respective information recording surfaces of the first to third optical disks. The optical pickup apparatus provides a wavelength dependency of a spherical aberration so as to correct a change in a spherical aberration due to a refractive index change with a temperature change of the objective optical element.
