We present the results of a study on Dual-Stage Deformable Mirrors using Zonal Bimorph Deformable Mirror (ZBDM) technology. A high density 'tweeter' DM has been assembled onto a lower density, high dynamic range 'woofer' DM to generate an integrated mirror which offers both high resolution and dynamic range simultaneously. Such a device has the potential to significantly simplify the design of astronomical Adaptive Optics (AO) systems. The latest developments are presented, including the fabrication of a small scale demonstrator.
