Beam Steering

Optotune’s disruptive 2D fast steering mirror solutions offer 2D beam deflection for LiDAR systems, machine vision, biometrics, diagnostics, metrology and 3D printing. Combining a 2D mirror for x/y with an electrically focus tunable lens enables 3D beam steering.

Our Products

Optotune provides innovative beam steering technology for applications requiring large angular deflection. Optotune 2D beam steering solutions can be used in reflection mode (2D mirror) or in transmission mode (tunable prism).

Optotune’s dual axis mirrors offer the benefit of large deflections and large mirror size in a compact package. The actuator is based on proven technologies, and built-in position feedback allows accurate control with a standard PID controller. The virtual rotation point of the 2D mirrors is close to the mirror surface which makes 2D scanning straightforward. Applications range from automotive (LiDAR, dynamic headlights, ADAS) and vision (field-of-view expansion, zoom) to biometric (eye-tracking), diagnostics and 3D printing.

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 a compact form factor can be achieved. The low absorption of the prism suits high-power applications, and 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 rapidly at any point within the addressable volume. This can be of interest for dynamic headlights, diagnostic and spectroscopic devices and 3D printing.

MR-10-30

MR-10-30-G-2 axis resonant

Optotune’s dual axis resonant mirror series MR-10-30 is the ideal choice for applications requiring 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 accurateposition read-out and control.

MR-15-30

MR-15-30-PS - 30 degree view

Dual axis mirror with position feedback.

Optotune’s dual axis mirror 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 technologies. 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.

MR-E-2

MR-E-2-PS - component 30 degree view

The MR-E-2 driver is an ideal solution for driving the MR-series 2D beam steering mirrors. It consists of a base unit containing control electronics and an integrated head unit with mirror and driving electronics.

The driver in the standard version with housings can be used for testing and proof of concept work. The boards without housing are available as OEM version for integration with system electronics.

TP-12-16

Tunable prism - 30 degree view

Tunable prism TP-12-16 for laser alignment and image stabilization.

The tunable prism is a tunable wedge that allows to tilt two optically flat and AR coated glass windows with respect to each other. The two glass windows are held together by a bellow structure that is filled with a low dispersion clear optical fluid. The core element can be integrated with a large variety of actuation principles such as mechanical or motorized lead screws, voice-coil and piezo actuators.
