Product description
The G&H AODF 4065 TeO₂ 635nm & 1550nm Acousto-Optic Deflector is designed for beam control applications requiring operation at both visible red and near-infrared wavelengths. It uses TeO₂ as the acousto-optic medium and is specified with polarization perpendicular to the mounting plane.
The device provides a 3 mm x 1.5 mm active aperture and is specified with a 50 Ohms nominal input impedance. Performance is defined at 635nm and 1550nm, with operating frequency, RF power, diffraction efficiency, beam separation and rise time values specified separately for each wavelength.
The AODF 4065 supports beam control in optical systems where dual-wavelength operation, collinearity, contrast and defined diffraction performance are important. It is suitable for specialist photonics platforms, optical instrumentation and OEM laser systems using visible red and near-infrared sources.
