摘要:
A microlens array including a plurality of spaced apart individual microlens in a plane defining a plurality of spaced apart apertures through the plane. The use of non-circular apertures in a preferred embodiment greatly increases the effective lens ration. This microlens array provides a dust-resistant optical element, and reduces the probability of flat spots resulting from an AR coating and problem associated with the edge effect resulting from electrolytic plating.
