Fast steering mirrors
Overview
Whether in R&D or in product development, Optotune’s disruptive 2D fast steering mirror solutions offer completely new design and integration possibilities.
Advantages:
Large clear apertures and beam 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
Customized coatings available
Dual axis fast steering mirror (FSM) with position feedback
Optotune’s dual axis fast steering mirror (FSM) offers the benefit of large deflections and large mirror size in a compact package. The actuator is based on proven voice-coil technology. A built-in position feedback allows it to be accurately controlled with a standard PID controller. The virtual rotation point of our 2D mirrors is close to the mirror surface which makes 2D scanning straight forward. We offer either two non-resonant axes or a non-resonant axis in combination with a resonant axis. The first option is ideally suited for vector scanning and point & shoot applications, the latter is ideal for fast raster scanning.
Optotune offers the MR-E-2, a full development kit including the mirror, control electronics and software.

Applications:
Machine vision (field-of-view expansion, zoom)
Free-space communication
Biometric (eye-tracking)
Metrology
3D printing
3D beam steering
Combining a 2D mirror for x/y with an electrically focus tunable lens allows you to direct your laser beam spot precisely and fast at any point within the addressable volume.
Application:
Adaptive headlights
Diagnostic/ophthalmic devices
Spectroscopic devices
3D printing
Tunable prism for laser alignment and image stabilization
In case working in reflection geometry is not an option, you may consider Optotune‘s tunable prism (TP). It is suitable for optical alignment of small angles in transmission. The core element can be combined with your preferred actuation method and achieve a compact form factor. The low absorption makes it suitable for high-power applications. Thanks to the low dispersion liquid it can also be used for polychromatic applications.
Applications:
Ophthalmic applications
Boresight alignment
Laser combiner
FOV expansion and AOI selection
Field-Of-View (FOV) expansion and Area-Of-Interest (AOI) selection with a MR-15-30 dual-axis VCM: The standalone camera on the right is equipped with a wide-angle objective to capture the overall scene. The camera on the left, equipped with a narrow-angle tele lens, looks onto the mirror and allows to “zoom-in” and select a small AOI out of a 100° optical FOV.
Applications:
Security applications
Surveillance and face-tracking in airports and other public spaces.
