Product description
At G&H, our UV acousto-optic deflectors (UV AODFs) are state-of-the-art solutions designed for high-speed scanning applications, offering precision, reliability, and unmatched performance. With decades of expertise, we lead the market in advanced designs tailored to demanding UV applications such as micromachining, inspection systems, via drilling, and graphic imaging.
Acousto-optic (AO) beam deflectors induce an angular shift of the diffracted first order proportional to the applied RF frequency carrier signal. The G&H AODF 4170-UV has 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.
Exceptional Diffraction Efficiency
With diffraction efficiencies typically exceeding 85%, the G&H AODF 4170-UV ensures optimal utilization of valuable UV photons. This high efficiency significantly enhances throughput and minimizes waste in critical applications.
Consistent Performance Across Scan Angles
Paired with our 6000 series RF driver, the G&H AODF 4170-UV offers the flattest diffraction efficiency versus frequency response, delivering consistent processing results across the full scan angle. This ensures reliable performance and repeatability in even the most demanding scanning applications.
Highest Optical Quality Crystals
G&H is renowned for producing crystal quartz with exceptional UV transmission. By sourcing or growing the highest-grade UV crystals, we maximize transmission, minimize beam distortion, and ensure unparalleled optical performance.
