Product description
The G&H AODF 4200-2 TeO₂ 442nm Visible Acousto-Optic Deflector is designed for beam steering and scanning applications in the visible spectral region. It uses TeO₂ as the acousto-optic medium and operates in a shear, off-axis acoustic mode.
The AODF 4200-2 is specified for 442 nm operation, with input polarization at 0° to the mounting plane and output polarization at 90° to the mounting plane. Its broad RF bandwidth and high scan angle make it suitable for applications where wide-range beam deflection and controlled optical performance are required.
The device includes anti-reflection coating on both sides and is specified with optical testing across the stated RF range at 488 nm. It is suitable for visible laser systems, precision scanning platforms, optical instrumentation and OEM photonics applications requiring controlled acousto-optic beam movement.
