Paper Abstract

Two of the many applications for microlens arrays are fill factor improvement in focal plane arrays and collimation of laser diode arrays. Most lenslet arrays made for fill factor improvement consist of immersion lenses that themselves do not have a 100 fill and the evaluation of such lenses is not representative of their use in an imaging system. Alternative designs are investigated. Anamorphic optics are required to correct for the astigmatism present in laser diode output. An array of micro-optics with toroidal refractive surfaces can be used to collimate or focus the light. We report on the fabrication and evaluation of such anamorphic micro-optics.
