Mid-Infrared Germanium Acousto-Optic Deflector AODF 4070 AODF 4070（锗）
The AODF 4070 germanium mid-infrared acousto-optic deflector is designed for beam deflection and scanning in the 9.4 µm band. It uses germanium as the acousto-optic interaction medium and operates in a longitudinal acoustic mode for high-precision mid-infrared beam control. Both input and output polarizations are parallel to the mounting reference plane, supporting stable, predictable integration into 9.4 µm laser systems. The RF system has a center frequency of 70 MHz and a bandwidth of 40 MHz for controlled acousto-optic deflection and scanning. The AODF 4070 uses a four-element phased-array structure with an integrated delay/beam-splitting module to support the required RF drive architecture and coordinated system control. It is water-cooled, has an 11 mm clear aperture and a 68 mrad scan angle, and is suitable for mid-infrared laser beam control, optical scanning, and specialized photonic systems. Model identification: AODF 4070 (germanium) (97-03260-04).
