Ultraviolet Acousto-Optic Deflector AODF 4170-UV
The AODF 4170-UV quartz acousto-optic deflector scans at 343 nm and 355 nm, with a 170 MHz center frequency, maximum 4.95 mrad scan angle, and aperture up to 7 mm. This advanced high-speed UV series offers precision, reliability, and performance for micromachining, inspection, via-hole processing, and pattern imaging. RF drive produces first-order angular deflection proportional to carrier frequency. AODF 4170-UV offers a maximum 7 mm standard aperture; custom versions accommodate beam widths above 60 mm. Typical scan ranges are about 5 mrad, supporting linear scanning or random-access positioning with fast, precise, repeatable control. High efficiency: AODF 4170-UV typically exceeds 85%, improving UV throughput and reducing losses. Full-range consistency: 6000-series RF drivers provide a flat efficiency response across the full scan angle for consistent, repeatable processing. Crystal quality: High-quality quartz, rigorous growth, and selection provide UV transmission and minimal beam distortion. Vertical manufacturing: G&H handles growth, polishing, coating, and packaging internally, with high-damage-threshold coatings and reliable mechanics for long-term consistency. Customization and scale: Custom design and volume production meet OEM performance and capacity requirements. Two-dimensional scanning: Two UV deflectors in series, supported by dual-channel drivers, provide stable, efficient two-dimensional beam control.
