| 1. A mold for an optical component comprising:
a first mold having a first mold curved surface that molds a first lens surface of the optical component;
a second mold having a second mold curved surface that molds a second lens surface of the optical component;
a first tapered surface which is rotationally symmetric about a first symmetry axis about which the first mold curved surface
is rotationally symmetric; and
a second tapered surface which is rotationally symmetric about a second symmetry axis about which the second mold curved surface
is rotationally symmetric, the second tapered surface contacting the first tapered surface such that the first symmetry axis
is aligned with the second symmetry axis,
wherein a curved surface distance is a distance between the first mold curved surface and the second mold curved surface and
a lens thickness is a distance between the first lens surface and the second lens surface, and
wherein the first tapered surface is elastically transformable and the second tapered surface moves to a position where the
curved surface distance is equal to the lens thickness, the second tapered surface elastically transforming the first tapered
surface to mold the optical component.
