Abstract

Low-cost adaptive optics is applied in lasers, scientific instrumentation, ultrafast sciences and ophthalmology. These applications demand the deformable mirrors to be simple, inexpensive, reliable and efficient. We report on a novel type of ultra-low-cost deformable mirror with thermal actuators. The device has response time of ~5 s, actuator stroke of about 6 μm, temporal stability of about λ/10 rms in the visible range and can be used for correction of rather large aberrations with slow changing amplitude.
