Deformable mirror optimized for low-order Zernike terms Print E-mail

Our new 19-channel piezo DM has been specially designed for correction of  low-order aberrations. By locating 18  of 19 mirror's actuators outside the 20-mm aperture, we achieved perfect correction of the first 15 Zernike polynomials practically without any actuator print-through.
