Product description
The G&H AODF 4080 TeO₂ 633nm Visible Acousto-Optic Deflector is designed for visible red wavelength beam control applications requiring reliable acousto-optic performance and predictable optical integration. It uses TeO₂ as the acousto-optic medium and is specified for 633nm operation.
The device provides a 2 x 2 mm active aperture and is specified with horizontal polarization to the mounting plane. The datasheet notes that the diffracted beam is vertically polarized for horizontal input, and horizontally polarized for vertical input, supporting defined polarization management within the optical system.
The AODF 4080 has an 80 MHz centre frequency and a 2 MHz RF bandwidth at -10 dB return loss. With anti-reflection coating to MIL-C-48497, specified optical power density, high contrast ratio and 85% diffraction efficiency at the specified beam diameter, it is suitable for visible red laser beam control, optical switching and precision photonics applications.
