Optotune’s compact fast and fine steering mirrors use robust voice-coil actuation to enable precise 2D beam deflection. Fast steering mirrors are designed for large tilt angles and include integrated optical position feedback for applications like field-of-view (FOV) expansion. ​
Fine steering mirrors offer an ultra-thin design with a large mirror surface, making them ideal for small, high-precision adjustments and laser wobbling.
- Large clear apertures and tilt angles​
- 2D beam deflection with a single optical element (reduced reflection loss, no beam-shift)​
- Robust voice-coil actuation​
- Optical real-time position feedback​
- Compact & lightweight
Fast steering mirrors (MR) redirect light by rapidly tilting a reflective surface around two axes. In Optotune’s fast steering mirrors, a voice-coil actuator generates smooth and precise motion with minimal wear, supported by a long-lifetime precision bearing. The virtual rotation point is positioned close to the mirror surface, ensuring accurate beam alignment with minimal lateral shift. A built-in optical position sensor provides real-time feedback for closed-loop PID control, supported by onboard calibration and temperature monitoring for stable long-term performance. With low-latency analog interfaces and a choice of high-power mirror coatings, Optotune’s fast steering mirrors deliver compact, reliable, and highly responsive 2D beam steering.
Optotune’s compact fine steering mirrors (FMR) use a voice-coil actuator placed around the reflective surface to enable precise 2-axis motion. A single large mirror provides true 2D beam steering for low- to high-power lasers with micro-radian resolution, while the bearingless design ensures long operational lifetime.
Optotune’s lightweight, compact fast steering mirrors (FSM) deliver large apertures with wide tilt angles, enabling true 2D beam steering using a single optical element—thereby reducing reflection losses, eliminating beam shift, and simplifying overall system design. When paired with a camera, the device enables field-of-view (FOV) expansion. A robust voice-coil actuator combined with real-time optical feedback ensures precise and repeatable motion control.
Optotune’s compact fine steering mirrors (FMR) deliver large apertures with small tilt angles in an ultra-compact footprint. Fast response times, high-power mirror coatings, and the ability to position a beam dump directly behind the mirror make these devices suitable for demanding applications such as 2D wobbling.
Fast steering mirrors
Fast steering mirrors from Optotune have the compactness and tip-tilt capability of a MEMS mirror, but the robustness of a Galvo mirror. Established voice-coil technology, combined with accurate optical feedback, enables many applications.
