Abstract:
1. A method for forming a lens, comprising the steps of: (i) supplying a dielectric body onto a substrate; (ii-1) causing a transfer surface of a mold to approach the dielectric body, the transfer surface having a concave portion or a convex portion in an aspherical shape for transferring an aspheric lens shape to the dielectric body; (ii-2) transferring the aspheric lens shape to the dielectric body by pressing the transfer surface to the dielectric body; and (iii) curing the dielectric body to which the transfer surface is pressed, so as to form a lens, an electric field being generated between the transfer surface of the mold and the substrate before any physical contact occurs between the transfer surface of the mold and the dielectric body in the steps (ii-1) and (ii-2), and in the step (ii-1), the dielectric body being attracted toward the transfer by the electric field.
