Isomet’s acousto-optic deflectors (AOD) are specifically designed to sequentially deflect a fixed laser beam. By changing the applied RF frequency, individual (random) positions can be approached as well as continuous lines can be generated.
Various models with different apertures and resolutions are available as well as single and dual-axis models, which allow simultaneous control in the vertical and horizontal axis. Corresponding HF drivers are also available.

FAQs
for Acousto-optic deflectors
An AOD is a device that deflects a laser beam using acoustic waves, changing the beam angle depending on the applied RF frequency.
An AOM primarily modulates the intensity or frequency of a laser beam, whereas an AOD varies the beam angle and is used for fast beam deflection.
They are used in laser scanning, optical traps for atomic physics, imaging, display technologies, and high-precision beam steering.
Typical deflection angles range from a few milliradians to several degrees.
The number depends on the frequency resolution of the driver; hundreds to thousands of angular steps are often possible.
The AOD is placed in the beam path, and the deflected beam is directed onto the target or a detector.
Radio frequency (RF) drivers with variable frequency are required to control the deflection.
Higher sound velocity allows faster deflection times but affects angular resolution.
Yes, AODs can deflect laser beams in microseconds or faster.
Sie ermöglichen die präzise Positionierung von Laserstrahlen zur Manipulation von Atomen in optischen Gitterfallen.
Yes, by combining two AODs, laser beams can be steered in two dimensions.
AODs are faster, wear-free, and enable more precise deflections without moving parts.
