摘要: An optical pickup includes a lens holder; an objective lens provided on the lens holder and having an effective region for collecting light from a light source and an edge located outer to the effective region; and a lens protector provided on the lens holder. The lens protector protrudes toward an optical disc more than the objective lens. The edge of the objective lens includes a convexed portion protruding toward the optical disc. An apex of the effective region of the objective lens protrudes toward the optical disc more than the convexed portion of the edge. A straight line connecting a part of the edge of the objective lens and a part of the lens protector is closer to the optical disc than the apex of the effective region of the objective lens.

摘要: An optical apparatus according to the present invention comprises an optical base having a bonding surface, and an optical component fixedly bonded to the bonding surface with an adhesive. The optical base has an open hole formed in the bonding surface. The open hole is filled with the adhesive. The optical component contacts the open hole so that a part of the open hole is left unclosed.
