FSM-K1 In Stock

The FSM-K1 by Newport is a Fast Steering Mirror (FSM) equipped with two axes, offering exceptional high bandwidth rotation with mechanical precision down to sub-microradian levels. This mirror utilizes voice coil technology to achieve minimal wear, outstanding accuracy, and exceptionally smooth motion around a gimbal point. The key to its remarkable performance lies in the unique flexure suspension design, which expertly confines the mirror's motion, yielding superior results. The FSM-K1 serves as an economical and highly effective solution for a wide range of commercial applications. These include image stabilization, tracking, laser pointing, and beam stabilization. This mirror does not have bearings, which effectively eliminating the common issues of striction and wear that are often associated with XY galvanometers.

The FSM-K1 offers a multitude of benefits and features, such as an extensive selection of mirror coating and substrate choices, resulting in low wavefront distortion. Its large aperture and high optical performance distinguish it from traditional galvo scanners. Notably, the mirror's rotational axes intersect at a single pivot point, a design choice that eradicates Pincushion Distortion and displacement jitter, setting it apart from dual XY galvos. Powered by four voice coil actuators, the FSM-K1 enables rapid and high-bandwidth rotation. When used in push-pull pairs, these actuators deliver balanced torque to the mirror, further enhancing its performance capabilities. Additionally, this mirror can be easily paired with a compatible OBP series Laser Beam Position Sensing Detector for swift laser beam control and stabilization when locked in position. The FSM-K1 has an impressive angular range of ±3°, a resolution of ≤2 µrad rms, and fast closed-loop control of up to 580 Hz.
