Optical pickup lens and optical pickup apparatus

An optical pickup lens focuses laser beams having different wavelengths λ1, λ2 and λ3 on at least three kinds of optical discs. At least one side of the optical pickup lens has a concentric loop zonal structure for compensating wavefront aberration occurring when recording or reproducing an optical disc having a substrate thickness t1 by the laser beam having the wavelength λ1 and wavefront aberration occurring when recording or reproducing an optical disc having a substrate thickness t2 by the laser beam having the wavelength λ2. When recording or reproducing an optical disc having a substrate thickness t3 by the laser beam having the wavelength λ3, a phase difference given to the laser beam having the wavelength λ3 due to the concentric loop zonal structure is about 0.15λ or smaller.
