Paper Abstract

We report fabrication of refractive microlens arrays in fused silica (SiO2) with a variety of pitches, diameters, and focal lengths. Typical f-numbers range from f/1.5 to f/5. Melted photoresist lenses are made on a fused silica substrate, and etched into the SiO2 using reactive ion etching (RIE) by carefully controlling the etch ratio. Techniques for microlens testing and measurement are discussed.
