Title:
WAFER LENS PRODUCTION METHOD
Document Type and Number:
WIPO Patent Application WO/2011/024745
Kind Code:
A1
Abstract:
The aim is to regulate thickness on the optical axis in the production of wafer lenses. Disclosed is a wafer lens production method that is equipped with a dispensing process for dropping resin onto a forming die (64), an imprinting process for pressing either the forming die (64) or a glass substrate (2) toward the other, and a releasing process for releasing the glass substrate (2) from the forming die (64), and that repeats the processing from the dispensing process to the releasing process as a single cycle and successively forms resin lenses (4) on the glass substrate (2); wherein the height (A) of the non-lens area (6) surrounding the lenses (4) and the height (B, C) of the glass substrate (2) are measured between the releasing process of a first cycle and the dispensing process of a second cycle, and the position of the forming die (64) is corrected for the imprinting processes of the second cycle on, on the basis of the heights (A-C).
