MICRO-LENS ARRAY WITH PRECISELY ALIGNED APERTURE MASK AND METHODS OF PRODUCING SAME

摘要

A micro-lens array with a precisely aligned aperture mask, and a method of forming the same, is provided. The aperture mask is formed by projecting light onto a mask layer using each lenslet in the micro-lens array. The intensity of the light and the mask layer material are chosen so that the light forms apertures in the mask layer via a non-ablative process. The resulting apertures are automatically aligned with their respective lenslets.
