MR-10-30
One-axis-resonant dual-axis fast steering mirror
Optotune’s one-axis-resonant dual axis fast steering mirror series MR-10-30 is the ideal choice for applications that require fast scanning and large deflection angles in a compact form factor. With a mirror size of 10 mm the MR-10-30 achieves up to ± 25° mechanical tilt in the linear axis and up to ±12.5° mechanical tilt in the resonant axis, resulting in a 100° x 50° field of view.
The mirror includes a position feedback system which allows accurate position read-out and control. The actuator is based on proven voice-coil technology and the resonant axis is solid-state. In contrast to galvo mirror systems, the virtual rotation point is very close to the mirror surface. The mirror can be fabricated with various coatings such as gold or protected silver.
The MR-10-30 is ideally suited for fast raster scanning. If you are interested in vector scanning and point & shoot applications, we recommend the MR-15-30 series.
Optotune offers the MR-E-2, a full development kit including the mirror, control electronics and software.

MR-15-30
Dual axis fast steering mirror with position feedback
Optotune’s dual axis fast steering mirror (FSM) series MR-15-30 is the ideal choice for applications that require large deflections in a compact form factor. With a mirror size of 15mm the MR-15-30 achieves up to +/- 25° mechanical tilt, which results in up to +/- 50° optical deflection. The mirror includes a position feedback system which allows it to be accurately controlled with a standard PID controller.
The actuator is based on proven voice-coil technology. In contrast to galvo mirror systems, the virtual rotation point is very close to the mirror surface. The mirror can be fabricated with various coatings such as gold, protected silver and other coatings including dielectrics on request.
The MR-15-30 is ideally suited for vector scanning and point & shoot applications. If you wish to do raster-scanning at higher speeds, we recommend the MR-10-30 series.
Optotune offers the MR-E-2, a full development kit including the mirror, control electronics and software.
