The Galvo motor selection begins with the component that is closest to your application, the mirror.

Considerations such as wavelength, power, beam diameter and spot size will dictate the best mirror for your application. Low inertia is essential for beam-steering mirrors to attain the highest accelerations, while high stiffness is needed to achieve adequate servo bandwidth. The reality, however, is that a balance must be struck between the two. That means selecting the best alternative from a large array of mirror designs, or creating a custom mirror that matches your performance requirements.
