Product description

G&H acousto-optic beam deflectors are state of the art, specialized designs for high-speed scanning applications.

Acousto-optic (AO) beam deflectors induce an angular shift of the diffracted first order proportional to the applied RF frequency carrier signal. Current devices will handle UV wavelengths down to 266 nm. Aperture heights of up to 7 mm Ø are offered while custom devices have demonstrated aperture widths exceeding 60 mm. Beam deflectors offer scan angles up to 5 mrad. These AO devices offer agile, accurate and reproducible, control of the beam position for linear scanning or randomly addressable beam positioning.

A variety of designs using optimized optical materials are available. Devices range from conduction cooled to high-power water-cooled designs. Our expert design staff can tailor deflector performance to meet your specific needs.

G&H UV deflectors are ideal for applications such as micro machining, inspection systems, via drilling and graphic imaging. Two-dimensional scanning can be achieved by cascading two deflectors in series.

As with all of our acousto-optic devices, the deflector line utilizes our high-quality crystals and AR coatings housed in a rugged and reliable package. The solid state design offers unsurpassed reliability and consistency.
