Acousto-Optic Beam Deflectors Quartz UV

SKU: AOBD

The AOBD Acousto-Optic Beam Deflectors offer non-mechanical, high-speed laser beam scanning up to 200 MHz, delivering precise position control with angular resolution in the nanoradian (nRad) range. The solid-state design ensures unmatched reliability and consistency, making these devices ideal for demanding applications requiring agile and accurate beam positioning. The AOBD operates by applying an RF signal to a phased array piezoelectric transducer, generating an acoustic wave inside the crystal. This wave forms a dynamic diffraction grating, which deflects an incoming laser beam at a specific angle when the Bragg condition is satisfied. By adjusting the RF driving frequency, the grating spacing changes, resulting in precise control of the diffraction angle. This mechanism enables random access beam positioning, continuous line scanning, and sequential point deflection with exceptional speed and accuracy. The AOBD series is specially optimized for UV wavelengths, supporting operation down to 266 nm. Available aperture include 3 mm, 5mm, and 7 mm, and they offer scan angles up to 5 mrad. Combined with our specially developed broadband RF drivers, the system supports advanced control methods such as frequency sweeping and chirping, enabling customers to quickly implement multi-functional scanning capabilities in a wide range of applications.
