Standa offers affordable piezoelectric deformable mirrors with
clear aperture of 30 mm and 50 mm. The full surface stroke is
6 µm standard with maximum stroke between the adjacent
actuators in the range from 1 µm to 3 µm. The mirror is controlled
by HV amplifer(s) and interfaced to a PC using 8-bit PCI or 12-bit
USB controller(s). The full-amplitude mechanical response of the
mirror is faster than 150 microseconds, but usually the response
time is limited to 1 ms by the control electronics. The surface can
be coated with a broad range of HR metal and multilayer dielectric
coatings. PDM`s easily integrates with Standa wavefront sensors
into a complete closed-loop adaptive optical system running with
frame frequency of 15 to 100 Hz. Applications include dynamic
correction of optical aberrations in laser, astronomical and
imaging systems.
