MANUFACTURING METHOD FOR ASPHERIC SHAPED ARTICLE AND ASPHERIC LENS ARRAY FORMED BY TRANSFERRING ASPHERIC SHAPED ARTICLE

摘要

PROBLEM TO BE SOLVED: To provide a method for forming a plurality of aspheric shaped articles on a substrate with high interval precision and reduced irregularity, and an aspheric lens array reduced in aberration and uniform in characteristics using the aspheric shaped articles as molds.;SOLUTION: Particles 30 comprising a predetermined material are applied to the surface of a flat substrate 10 having a plurality of spherical or almost spherical recessed parts 20 formed to its surface from an inclined direction while rotating the flat substrate 10 around a rotary shaft 14 vertical to the surface of the flat substrate 10 under vacuum to form a film and the shape of the spherical or almost spherical recessed parts are processed to be adjusted to a desired aspheric shape. These aspheric recessed parts are used as molds to be filled with a transparent material having flowability and this transparent material is cured and released to form the aspheric lens array.;COPYRIGHT: (C)2005,JPO&NCIPI
