Abstract

The cost of good, reliable deformable mirrors has made them inaccessible to the astronomical community and other would-be commercial users. Historically, the deformable mirror has cost nearly $DOL2500. per channel and comprised about 25% of the cost of an adaptive optics system. Xinetics has created a deformable mirror technology which costs less than $DOL1000. per channel including the electronic driver. In addition, the mirrors feature novel actuator cartridges which contain a simple thermal mechanism to allow simple replacement of damaged actuators. The current mirrors use piezoelectric actuators for broad temperature response and operate at 100 volts. They feature 7-mm interactuator spacing, 4- micrometers displacement, and interactuator coupling tailorable between 5 to 15%. Complete NASTRAN and Weibull analyses has been conducted to insure sufficient safety margin. The results of the 37, 97, and 349 channel mirror manufacturing efforts are reported in this paper.
