Title:
MANUFACTURING METHOD OF OPTICAL ELEMENT AND PROCESSING METHOD OF MOLD FOR OPTICAL ELEMENT
Document Type and Number:
Japanese Patent JP2006076235
Kind Code:
A
Abstract:

To provide, in manufacturing an optical element having high permeability for short wavelength light and little in birefringence by molding a resin composition, a method for manufacturing the same which does not cause defects on the optical element even if the mold is repeatedly used over a long period of time.

In the method for manufacturing the optical element by molding the resin composition containing a polymer having an alicyclic structure by using the mold, there is formed a layer of ≥3 nm and ≤20 nm of a fluorine containing compound on the contact surface between at least either of a first mold member and a second mold member which constitute the mold and a member molding space.
