Acousto-Optic Deflectors

Acousto-Optic Deflectors

Brimrose 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.
