RESIN OPTICAL COMPONENT AND PROCESS FOR PRODUCING THE SAME

摘要

A process for producing a resin optical component in which a light shielding layer can be formed easily. A laser light is focused at an arbitrary position within resin exhibiting a high light transmittance and energy is concentrated thereat, thus generating a micro-spotty discolored part through carbonization of resin. A light shielding wall exhibiting a high light absorbance is formed within the resin exhibiting a high light transmittance by forming a multiplicity of micro-spotty discolored parts within the resin. The light shielding wall can remove a stray light, i.e. a light incident obliquely to a lens, passing through a lens array plate in the thickness direction and leaving a proximate lens at the outgoing side thereof.
