Title:
APPARATUS FOR MANUFACTURING OPTICAL ELEMENT AND METHOD FOR MANUFACTURING OPTICAL ELEMENT
Document Type and Number:
WIPO Patent Application WO/2012/173025
Kind Code:
A1
Abstract:
Provided is an apparatus for manufacturing an optical element, and a method for manufacturing an optical element, whereby variance of dropping positions of glass droplets can be suppressed even with a low-cost and simple configuration. The positions where the glass droplets are discharged from a discharge port (51c) are controlled by having a predetermined force applied to the glass droplets from the wall surface of a path (51b) of a correcting member (51) in a non-contact manner, said glass droplets passing through the path (51b). Therefore, variance of dropping positions of the glass droplets can be suppressed without surrounding the whole manufacturing apparatus. Consequently, a highly accurate optical element can be manufactured with the low-cost and simple configuration.
