         List of Products             Acousto Optical Deflectors
 

Acousto-optic beam deflectors (AOBD) offer precise angular control of an optical beam using RF drive frequency tuning. Up to two thousand spots can be resolved over an angular range of a few degrees for 1D and 2D scanning as well as beam deflection through a fixed angle. The scan speed can be as fast as a few microseconds.
Beam deflectors offer highly uniform diffraction efficiency across the full scan angle, with consistent power throughput for scanning applications such as material processing and digital imaging. We manufacture devices based on tellurium dioxide crystals grown in-house for visible and near-infrared (NIR) wavelength applications. For optimal transmission in the ultraviolet (UV) we offer fused silica and crystal quartz products. For broad bandwidth applications, we use a longitudinal mode approach with a phased array of piezoelectric elements within the transducer. We achieve high efficiency with slow shear deflection using parallel tangents off-axis interaction.

STBR series beam deflectors
STBR series Acousto-Optic Deflectors (AODs) combined with RF drivers are specially designed for high-speed scanning applications such as laser recording, optical scanning, signal processing, etc. The AOD changes the diffraction angle of an input laser beam and its angular position is linearly proportional to the RF frequency, so that the higher the frequency, the larger the diffracted angle.
