We present a compact adaptive glass membrane lens for higher order wavefront correction and axial scanning, driven by integrated segmented piezoelectric actuators. The can be deformed in combination of rotational symmetry providing focus control up to ± 6 m-1 spherical aberration 5 wavelengths different discrete symmetries correct aberrations such as astigmatism, coma trefoil 10 wavelengths. Our design provides large clear aperture 12 mm at an outer diameter the actuator 18 mm, thickness 2 response time less than ms.
