Die for forming a micro-optical element, manufacturing method therefor, micro-optical element and manufacturing method therefor.

摘要

A die which can press-mold an accurate glass micro-optical element such as a grating repetitively can be manufactured easily by adhering a thin film, having an inverse shape of the master of a micro-optical element, on the top flat plane of a hard base body and by forming a protective layer thereon. The die having an inverse shape of the master can press-mold glass repetitively. By press-molding glass with the die, reliable glass micro-optical elements of the same shape as the master can be produced in a large amount and at a low cost. <IMAGE>
