Abstract

Refractive microlens arrays with f numbers ranging from f/1 to f/5 have been fabricated using a melted photoresist technique. The photoresist surface profile has been accurately reproduced in the underlying SiO2 substrate using etching techniques. Surface profile and optical performance characteristics of these microlenses are reported. Spherical microlenses are shown to have nearly diffraction-limited performance.
