Abstract
Modern bio-imaging techniques such as light-sheet and PALM/STORM are now aiming to image more complex biological samples at larger depth and therefore face larger-amplitude and more complex aberrations. Here we will present our newly-developed deformable mirror which addresses these challenges. It is a continuous-membrane deformable mirror with 91 centro-symmetrically-arranged electromagnetic actuators, which is much more efficient for correction of both low and high-order aberrations compared to square layout, used in the past. Mirror has 99.7% linearity and almost no hysteresis, which ensures exceptional precision and speed in closed-loop mode as well as accuracy and unrivaled temporal stability in open-loop mode.
