摘要

PROBLEM TO BE SOLVED: To provide an optical pickup wavefront aberration inspection apparatus highly accurately measuring an optical pickup having satisfactory aberration performance in a short period of time by a simple optical system, to provide an optical pickup assembly adjustment device and to provide a lens evaluation device, a lens assembly device and an objective lens actuator assembly adjustment device for the optical pickup.;SOLUTION: In the wavefront aberration inspection apparatus, a position in the horizontal direction of the optical pickup is adjusted to minimize the tilt component of a phase wavefront of light emitted from the optical pickup detected by the wavefront aberration detection means, to measure the wavefront aberration of the light emitted from the optical pickup. Thereby, e.g. an optical pickup wavefront measuring device for highly accurately measuring wavefront aberration of the light emitted from the optical pickup can be constituted with a simple system and alignment in a horizontal direction during aberration measurement can be performed in a short period of time.;COPYRIGHT: (C)2009,JPO&INPIT
