Apparatus for Manufacturing Wafer Lens, Molding Die, And Method for Manufacturing Wafer Lens

摘要

An invention for producing a wafer lens is disclosed in which a cured resin is prevented from having projection portions or unfilled sections. The method comprises a dispense step in which resin is dropped onto a die having plural cavities arranged to leave spaces therebetween, an alignment step in which the positions of the die and a glass substrate are adjusted, an imprint step in which one of the die and the glass substrate is pressed against the other, a curing step in which the resin is cured, and a release step in which the glass substrate is released from the die, the steps from the dispense step to the separation step being repeated as one cycle to successively form plastic lens portions on the glass substrate, wherein in the alignment step in each cycle, the cavities of the die are placed between the formed lens parts.
