Resin-cemented optical element, mold therefor, fabrication process thereof, and optical article

摘要

The present invention provides a resin-cemented optical element comprising a base member 10 and a resin layer 11 formed on the surface of the base member; the resin layer 11 being in a thickness of 300 μm or smaller at least at some part of a peripheral portion (i.e., a region within 1 mm from the peripheral edge face 17 of the resin layer 11, or a region outside an effective-diameter region), and being in a thickness 12 of 850 μm or larger at a position which is thickest in the resin layer; a mold therefore; a manufacturing method thereof; and an optical article having this optical element.
