Paper Abstract

The performance of microelectromechanical systems deformable mirrors (MEMS DMs) continues to improve in areas of stroke, open-loop positioning, actuator count, and drive electronics. However, a key area lacking in the development of these devices is good optical coatings suitable for a broad spectrum of applications and wavelengths. This paper discusses the progress Iris AO has made towards coating its MEMS DMs with gold, protected aluminum, protected silver, and dielectric coatings.
