The FSM-300-01 Fast Steering Mirror System provides two-axis, high-bandwidth rotation with sub-microradian resolution in a standard, economically viable design for commercial use in applications such as laser beam stabilization, laser pointing, tracking, and image stabilization. Using a unique flexure design to confine the motion of the mirror, the bearing surfaces often used with galvanometer scanners are eliminated. This results in ultra-smooth motion, very high accuracy, and practically infinite lifetime. Four voice coil actuators provide fast, high-bandwidth rotation. Utilized in push-pull pairs, the actuators provide smooth, even torque to the mirror. An internal optical-based feedback loop provides position feedback for accurate and stable pointing and tracking. The included controller/driver establishes the feedback interface between the angle sensors and the drivers, providing current to the voice coils that tip and tilt the mirror assembly. It also provides a convenient interface between the user and the mirror, allowing control voltages to be applied and mirror position to be monitored. The updated FSM-CD300 Series Controller incorporates upgraded independent gain and DC offset adjustments of both X and Y-axes. This enhancement significantly improves the system performance for Laser Pointing applications, requiring accurately controlled point-to-point movements. The FSM300-01 comes with a 1 inch (25.4 mm) diameter ER.1 coated mirror. A wide range of 1 inch mirror assemblies are sold separately. This allows the user to field replace the standard mirror with a better coating option if required.
