METHOD AND DEVICE FOR PRODUCING FINE SHAPED FORM, AND DIE AND OPTICAL ELEMENT

PROBLEM TO BE SOLVED: To provide a die having a surface on which many fine and highly accurate shapes are formed by a simple and inexpensive process and also to provide a molded article having anti-reflection function using the die by a simple and inexpensive process. SOLUTION: A ground and polished convex surface is formed on a stainless steel die, and a convex die transcription surface 2a is formed by film-forming of non-crystalline alloy on the convex surface. The die 2 is heated at an appropriate temperature higher than a glass transition point of the non-crystalline alloy film but lower than a crystallizing temperature, and under the temperature condition, a die transcription surface (convex surface) 2a is formed under pressing by microwave pressing means, whereby a pattern 20 comprising many fine conical concaves 2b is formed. On a concave surface of a plastic lens formed by injection molding, a pattern comprising many fine conical projections is formed on the concave surface. The concave surface of thus produced lens has sufficient anti-reflection property. COPYRIGHT: (C)2008,JPO&INPIT
