Abstract
Microlens and microlens arrays have been successfully produced using sensitized gelatin and Nd:YAG laser at 532 nm. Obtained microlenses are divergent (negative), with parabolic profile and 600 &mgr;m useful aperture diameter. Microlenses have near diffraction limited performance with resolution more then 50 cycles/mm for the total field of view (2&ohgr; = 18°). Single microlens is manufactured in just a few seconds using 60 mW unfocused Nd:YAG laser beam.
