Abstract

THIS INVENTION AIMS AT GUARANTEEING THE PRECISION OF AN ADHERING POSITION WHEN A LENS TO BE MACHINED IS TO BE ADHERED AND FIXED TO A LENS HOLDING MEMBER WITH AN ADHESIVE BY HEATING THE LENS HOLDING MEMBER. AN OPTICAL ELEMENT HOLDING METHOD DURING MACHINING , OF HOLDING AN OPTICAL ELEMENT SUCH AS A LENS WITH A HOLDING MEMBER DURING MACHINING THE OPTICAL ELEMENT, IS CHARACTERIZED IN THAT WHEN THE OPTICAL ELEMENT IS TO BE HELD AT AN OPTICAL ELEMENT HOLDING POSITION OF THE HOLDING MEMBER WITH AN ADHESIVE, THE SPACE BETWEEN THE OPTICAL ELEMENT HELD AT THE HOLDING POSITION AND SAID HOLDING MEMBER COMMUNICATES WITH OUTER AIR. WITH THIS METHOD, WHEN AIR IN A LENS HOLDING SPACE IS HEATED UPON HEATING THE LENS HOLDINGS MEMBER IN ORDER TO SOFTEN AN ADHESIVE TO BE APPLIED TO THE LENS HOLDING MEMBER, AN ERROR IN PRECISION OF THE LENS ADHERING POSITION IS PREVENTED, AND THE LENS CAN BE MACHINED ACCURATELY.
