1. A method for fabricating an arrayed optical element, comprising the steps of:
(a) forming a light blocking frame using a first material, the first material being one of a material with low light transmittance and a non-light transmissive material, and having a heat deflection temperature, the light blocking frame including a bottom plate that is formed with a plurality of through holes arranged into an array, a surrounding wall that is integrally connected to the bottom plate and that extends in an upward direction along an optical axis, and at least one partition wall that is integrally connected to the bottom plate and the surrounding wall and that extends in the upward direction, the surrounding wall and the at least one partition wall cooperating to define a plurality of spaced apart optical channels, each of the optical channels being in spatial communication with a respective one of the through holes; (b) placing the light blocking frame thus formed in step (a) into a cavity of a mold; and (c) injecting a second material into the mold to form a lens unit that is integrally connected to the light blocking frame, the second material being an optical plastic material and having a forming temperature lower than the heat deflection temperature of the first material, the lens unit including a substrate that has a top side abutting against a bottom side of the bottom plate of the light blocking frame, and a plurality of upper positioning walls that are integrally connected to the top side of said substrate and that extend in the upward direction, the substrate including a plurality of lens elements, each of which is aligned with a respective one of the through holes, each of the upper positioning walls having an inner side that abuts against an outer side of the surrounding wall, a top side of each of said upper positioning walls being not lower than the top side of said surrounding wall in the upward direction. |
