The Multi-DM: A versatile， robust deformable mirror system for advanced wavefront control

The popular and versatile Multi-DM offers sophisticated aberration compensation in an easy-to-use

package. With 140 precisely controlled elements and low inter-actuator coupling， this system is

ideal for a broad range of applications including as microscopy，

retinal imaging， and laser beam shaping. The high speed， high

precision driver electronics are easily controlled via USB

interface. The DM is available in both continuous and

segmented surfaces for adaptive optics or spatial light modulator

applications. The DMs are capable of up to 5.5 μm stroke， 20 kHz

frame rate*， have sub-nm step size， and zero hysteresis.

* 1.5 μm DM and SLM capable of 20 kHz.
