Abstract

A novel multi-focusing curved microlens array (MLA), inspired by compound eyes, was fabricated using a homebuilt mold in this paper. By gas-assist deformation, and using the PDMS film as the template, MLA with variable focal length were fabricated through the different apertures of the micro-stomatas attached on the mold. Fabricated in one step, without reverse mould process, makes the whole fabrication process simple, cost-effective and deformation less. The ultraviolet curing adhesive NOA81, which was cured in seconds, has excellent optical performance and a wide operating temperature range. The optical performances of the MLA were demonstrated by optical experiments and simulation.
