    摘要: A lens surface of an objective lens includes an optical surface formed of a plurality of annular optical surfaces which include an approximately stair-shaped cross section and which are annularly partitioned centered around an optical axis of the objective lens, and a plurality of connecting surfaces that connect the plurality of mutually adjacent annular optical surfaces to each other. The plurality of connecting surfaces include cylindrical connecting surfaces formed of a cylindrical surface centered around the optical axis and a conical connecting surface formed of a conical surface centered around the optical axis, and the conical connecting surface connects the annular optical surface and the annular optical surface.

    摘要: A mold manufacturing method for manufacturing a mold with which a diffractive lens array of high accuracy can be molded by the following steps: creating a set of coordinates of form points indicating a form of a concave portion which has a saw-toothed surface; deriving a set of coordinates of moving points by moving the coordinates of each of the form points; deriving an orbit for forming the concave portion, based on the moving points; and fabricating a metal mold by forming the concave portion which has a center that does not match a rotation center of the work piece, by moving a cutting tool along the orbit while rotating the work piece so as to cut the work piece.
