MULTI-ELEMENT OPTICAL SUBSTRATE AND ITS PREPARATION METHOD, LENS MODULE USING THE MULTI-ELEMENT OPTICAL SUBSTRATE |
摘要 |
A multi-element optical substrate preparation method includes the steps of: a) preparing a first element having a center hole and a core positioning device defining a first element center line; b) preparing a mold having a mold cavity and a cavity center line, and then placing the first element in the mold to keep a predetermined part of the first element in contact with the mold cavity; c) calibrating the position of the core positioning device of the first element in the mold cavity subject to the reference of the cavity center line of the mold; d) filling a transparent plastic material into the mold cavity of the mold for enabling the transparent plastic material to be molded on the first element and cured into a second element so that the first element and the second element form an optical substrate; and e) opening the mold and taking the optical substrate out of the mold.
