AOBD – UV Acousto-Optic Beam Deflector for UV systems
2690 | 3246 | 3283
Beam Deflectors are 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 are offered as well as aperture widths over 60 mm. Beam deflectors offer scan angles up to 5 mrad. These AO devices offer accurate, agile control of the beam position for linear scanning or random frequency hopping.
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.
