Paper Abstract

Diffraction microlens arrays has been fabricated in silica substrates by deep UV photolithography and wet chemical etching. The calculated kinoform profile has been approximated by multistep function and this microrelief has been transfered into the surface with wet etching through the photoresist mask. The diffraction efficiency of eight-level kinoform microlens is as high as 85%.
