Product description
The G&H AODF 4055 TeO₂ 0.68–1.30µm Acousto-Optic Deflector is designed for laser beam control applications requiring operation across visible red and near-infrared wavelengths. It uses TeO₂ as the acousto-optic medium and operates in a shear, off-axis acoustic mode.
The device is specified with input polarization at 0° to the mounting plane and output polarization at 90° to the mounting plane. Its RF configuration is centred at 55 MHz, with a 40 MHz transducer RF bandwidth, supporting controlled optical deflection across the operating range.
The AODF 4055 includes anti-reflection coating specified for 0.63–1.06µm, low insertion loss and a defined active aperture. Wavelength-specific notes define frequency range, separation angle and RF power values for 0.68µm, 0.95µm and 1.30µm operation, supporting integration into multi-wavelength beam control systems.
