Visible Acousto-Optic Deflector AODF 4140
The AODF 4140 quartz 532 nm visible-light acousto-optic deflector is a high-performance quartz-crystal beam-control device for deflection and scanning in the 515–532 nm green band. Longitudinal acoustic operation provides stable, reliable visible-light modulation and control. Both input and output polarizations are at 90° to the mounting plane for predictable integration and stable coupling. A dual-element phased array improves deflection precision and system scanning stability. The AODF 4140 has a 7 mm clear aperture for standard green-laser paths, with scanning performance and nominal efficiency defined at 532 nm. Water cooling supports active laser systems requiring thermal management. Applications include stable beam control and precision scanning in green-light systems, optical instruments, and OEM photonic platforms.
