CASTECH 2D Acousto-Optic Deflectors (2D-AODs) are engineered for high-speed solid-state laser beam scanning without mechanical inertia. By varying the RF driving frequency, the system enables precise beam steering with random positioning, continuous line scanning, and sequential point deflection. With scan rates exceeding 200 MHz and nRad-level position control, these devices provide exceptional speed and accuracy for advanced photonics and semiconductor applications.
