Gradient Index Lens Array Through-focus Modulation Transfer Function Modeling

Abstract

Radial gradient index (GRIN) fiber lenses are becoming more and more common in a variety of optical devices, especially photocopying machines. In these machines arrays of GRIN lenses are used to form compact unity magnification lenses. These arrays are commercially available from the Nippon Sheet Glass Co. under the trade name SELFOC1 lens array, or SLA.
