Microjet fabrication of microlens arrays

摘要

Microjet, or inkjet, technology is used to fabricate lenslet arrays with packing densities greater than 15000/cm/sup 2/. Typical lens diameters range between 70 and 150 /spl mu/m, and focal lengths are between 50 and 150 /spl mu/m. Individual lenslets are characterized in the Fraunhofer plane. The full array is characterized in its far field.
