摘要
A method of molding a plastic element having a microstructure embedded therein includes the steps of providing a master having a microstructure therein; casting a liquid surface coating over said master; solidifying the liquid surface coating to form a rigid molding tool containing said microstructure; placing the molding tool into a molding machine; introducing a plastic element into the molding machine; transferring the microstructure from the molding tool to the plastic element; and removing the molded plastic element from the molding machine. The molding tool may also be produced by machining directly into a molding base element a predetermined microstructure without machining through a transfer interlayer. An injection-molded binary optical element produced according to the method of the present invention provides an injection molded optical element which diffracts light.
