Acousto-optic Medium: Germanium Spectral Range: Far-Infrared Operating Wavelength: 9100 - 9500 nm

The AODF 4050 germanium acousto-optic deflector is designed for mid-infrared laser modulation and beam-control applications in the 9100–9500 nm band. It uses germanium as the acousto-optic interaction material and operates in a compressional acoustic mode. Its optical configuration uses linear horizontal polarization parallel to the base and supports stable operation over an RF frequency range of 40–60 MHz. Low-reflection antireflection coatings provide high transmission within the specified band to reduce optical loss. The AODF 4050 has an 11.6 mm clear aperture, high diffraction efficiency, and defined beam-separation characteristics at 9.4 µm, making it suitable for precision modulation and beam control in mid-infrared laser systems. It is water-cooled and equipped with push-in connectors for integration into high-power laser systems. Model identification: AODF 4050 (germanium) (97-03477-01).
