We have developed a novel $\mathbf{512\ x\ 320}$ micro mirror array consisting of 2axis-tip-tilt actuators with $\mathbf{48}\mu\mathbf{m}$ pixel size, allowing a continuous, pure tip-tilt motion up to 3.5° in arbitrary directions, fully calibratable with standard deviations of better than 0.025°. The device is realized in a fully CMOS compatible process with an underlying integrated address circuitry.
