Abstract
A new technique of microlens array fabrication based on the use of exc imer laser radiation is described. Poly(methyl methacrylate) (PMMA) su bstrates are treated with many low-energy KrF laser pulses and exposed to styrene vapor. The irradiated material swells, producing spherical microlenses that are stabilized by UV polymerization. The chemistry o f this process and the optical quality of the lenses are discussed.
