摘要:
An objective lens used for an optical information recording/reproducing apparatus for an optical disc based on a predetermined standard is made of resin and has a numerical aperture larger than or equal to 0.75. When f (unit: mm) represents a focal length at a wavelength λ (unit: nm), d (unit: mm) represents a thickness, and n represents a refractive index of the objective lens at the wavelength λ, the objective lens satisfies following conditions: 1.00
