Advanced laser systems require fast and precise beam steering solutions without mechanical inertia to achieve flexible scanning, accurate positioning, and high-speed operation. Engineers need optical deflection devices that provide reliable control across different wavelengths and demanding applications.

CASTECH 2D-AOD utilizes acousto-optic technology to enable high-speed laser beam scanning by controlling RF driving frequency, achieving random positioning, continuous line scanning, and sequential point deflection with nRad-level position control. With high diffraction efficiency, wide scanning angles, and customized designs for different crystals, wavelengths, and beam sizes, CASTECH AOD solutions support complex optical systems requiring dynamic beam control.
