 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. |
