The Hi-Speed DM37 manufactured by Alpao is a 7.5-mm deformable mirror designed for beam-shaping and vision-sciences applications, and for others that require correction of large aberrations. The low-surface-error, large-stroke (more than 35 μm for astigmatism and focus wavefront correction) mirror has an optical silver-protected coating. It is supplied with certified drive electronics for precise control. Drivers for Matlab, LabView and C/C++ are included. Nonlinearity errors are <3%, and settling time is 1 ms at ±5%.
