Product description
The G&H AODF 4120-3 TeO₂ 413nm Visible Acousto-Optic Deflector is designed for beam control applications requiring reliable optical deflection in the visible spectral region. It uses TeO₂ as the acousto-optic medium and operates in a shear, off-axis acoustic mode.
The AODF 4120-3 is specified with horizontal input polarization and vertical output polarization, supporting defined optical integration within visible laser beam steering and scanning systems. Its RF configuration is designed around a 120 MHz centre frequency, with impedance matching specified across the operating frequency range.
With its compact active aperture, low RF power requirement and defined diffraction performance, the AODF 4120-3 is suitable for specialist visible laser systems, scientific instrumentation and OEM photonics platforms requiring precise acousto-optic beam control.
