STEERING STAGE
Fast tip and tilt steering stage MTS2A23H6mf6000
A compact steering stage for laser satellite communication
Satellite communication was once the domain of radio waves, but laser based methods have been proposed and demonstrated in many places in recent years. Conventional microwave communication faces a clear problem: the available frequency bands are running out.
Optical communication raises the data rate enormously, and because the signal travels as a focused laser beam there is little concern about interference or eavesdropping. We want to help make that technology practical and widespread.
We have more than 20 years of experience driving piezoelectric actuators, and we design, manufacture and sell them in house. This steering mirror controls mirror angle accurately at high speed, and we hope it helps satellite communication spread further.
