The H-412 from L3Harris Technologies is a Tellurium dioxide (TeO2) Acousto Optic Modulator (AOM) that operates at a wavelength of 488 nm - 800 nm. It has a nominal center frequency of 105 MHz and diffraction efficiency of over 80%. This AOM has a deflection bandwidth of 95 MHz - 115 MHz and total deflection angle of 2.32 mrad. It has a rise time of up to 30 ns, an on/off contrast ratio of 30 dB, and optical beam diameter of 0.15 mm - 3.5 mm (H) x 0.35 mm (V). This AOM uses advanced coherent transducer array technology and can be operated in either the RF phase modulation mode or a conventional on/off pulse RF mode. It is available in a module that measures 1.95" (L) x 1.5" (W) x 1" (H) and is ideal for optical modulation in visible and near-infrared (NIR) systems requiring the ultimate in beam pointing stability, and predeflection, modulation, pointing adjustment & micromachining in visible & NIR laser systems.
