の範囲第１項記載の平行光束の環状集光レンズ。[Claims for Utility Model Registration] (1) A basic convex lens is cut along a plane passing through its optical axis, and in this plane, a first straight line parallel to the optical axis, and , a first plane surrounded by the first straight line and a second straight line on the opposite side with respect to the optical axis, the second straight line, and parallel to the optical axis, and , a third straight line on the opposite side of the second straight line or on the optical axis with respect to the optical axis, and a second plane surrounded by these, 1 plane and the second plane, among the sides constituting them, the second plane
A third plane is formed by joining the sides formed by straight lines so that the first plane and the second plane are the same plane and are opposite to each other with the second straight line as a boundary. 1. An annular condensing lens for parallel light flux, characterized in that it is a rotating body obtained by assuming a plane and then rotating the third plane about the first straight line constituting the third plane. (2) In the rotating body obtained with the first straight line as an axis, the two-dimensional qualitative distribution on the third plane becomes a three-dimensional qualitative distribution as it is.Claim 1 of the Utility Model Registration Claim An annular condensing lens for parallel light flux as described.
