These devices integrate the mirror, mount, and motor for inertial balance. Mirror selection is based on operating wavelength, power, and beam diameter/spot size. The mirror-mount configuration is determined for multiple mirror orientations and field service, and is paired with a motor based on overall design goals. The optimized mirror designs come in a clear aperture range of 4 to 50 mm, including beryllium and silicon-carbide for greater stiffnesstoinertia ratio. Mirror-mounting designs include direct mounting to the rotor shaft, sleeve-mount, tapered-mount, and integrated mirror-mount.
