Microjet fabrication of microlens arrays

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