Abstract
Micro-mirror arrays configured for use in a variable focal length lens are described herein. An example variable focal length lens comprises a micro-mirror array having a plurality of micro-mirror elements arranged in at least a first section and a second section. Each micro-mirror element has a tilt axis and comprises, on each of two opposing sides of the tilt axis, (i) at least one actuation electrode, (ii) at least one measurement electrode, and (iii) at least one stopper. Additionally, each micro-mirror element in the first section has a first tilt angle range, and each micro-mirror element in the second section has a second tilt angle range, with the first tilt angle range being less than the second tilt angle range.
