Acousto-Optic Deflectors

Perfectly suitable for all scanning and random access deflector inserts

Unlike relevant intensity modulators and fixed frequency shifters, acousto-optic deflectors from Polytec are equipped with a phased array controller. As a result, a high diffraction efficiency is maintained even when the diffraction angle is varied by means of changing the control frequency, without any need to also adjust the angle of incidence at the same time during this process. Acousto-optic deflectors from Polytec are available for laser wavelengths in the visible and near-infrared ranges.
