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.
