- Steering mirrors
FMR series
Optotune’s compact FMR Series 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 bearing-free design ensures long operational lifetime.
Product variants
With a 20×20 mm2 mirror size the FMR series offers precise beam control with a large clear aperture and fast response. Its compact design, high-power coatings, and ability to position a beam dump directly behind the mirror make it ideal for demanding applications like 2D wobbling.

Common applications:
LiDAR, FOV expansion, AOI selection, medical laser treatment, free-space optical communication (FSOC), laser processing, biometric (eye-tracking), ophthalmology (fundus camera, OCT), 3D printing
Optotune’s lightweight, compact Fast Steering Mirrors deliver large apertures with wide tilt angles for true 2D beam steering using a single optical element—reducing reflection losses, eliminating beam shift, and simplifying system design. Paired with a camera, it enables FOV expansion. A robust voice-coil actuator and real-time optical feedback ensure precise, repeatable motion control.
