Optotune is developing 2D beam steering solutions that can be used in reflection mode (2D mirror) or in transmission mode (tunable prism).

Dual axis voice coil mirror (VCM) with position feedback
Optotune’s dual axis voice coil mirror (VCM) 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. The standard configuration is non-resonant (quasi-static) on both axis. Please contact Optotune if you require faster speed with resonant scanning.

Applications range from automotive (LiDAR, dynamic headlights, ADAS) and vision (field-of-view expansion, zoom) to biometric (eye-tracking), diagnostics and 3D printing.

Tunable prism for laser alignment and image stabilization
Optotune‘s tunable prism (TP) is suitable for optical alignment and beam-steering 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.

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. This can be of interest for dynamic headlights, diagnostic and spectroscopic devices and 3D printing.
