Deformable Mirror (DM-140.37)
A beam leaving a laser has poor spot quality and cannot be guaranteed to propagate perfectly parallel, due to errors in laser components, material inhomogeneity, and interference within the beam itself. Adaptive-optics wavefront sensors and wavefront correctors (deformable mirrors) are therefore used for real-time wavefront correction. The precision device performing this correction, the deformable mirror, is among the most difficult products to design in micro- and nanoscale motion control.
