Ultraviolet Acousto-Optic Modulators AOMO 3200-1999
AOMO 3200-1999 is an ultraviolet acousto-optic modulator using a quartz-crystal acousto-optic medium. Designed for precise beam control in 257–266 nm deep-ultraviolet laser systems, it provides stable optical switching, pulse control, beam gating and dynamic intensity modulation. High optical efficiency, low-loss transmission and reliable modulation meet switching-stability and repeatable-control accuracy requirements in demanding ultraviolet photonic systems. The excellent ultraviolet optical properties and stable acousto-optic characteristics of crystalline quartz allow AOMO 3200-1999 to provide efficient, reliable beam modulation for deep-ultraviolet laser applications. Its larger square aperture suits systems with larger focused-beam diameters, while antireflection (AR)-coated optics and high switching contrast provide clear beam control and efficient ultraviolet transmission. Applications include ultraviolet micromachining, semiconductor manufacturing, spectral analysis, life-science instruments, analytical systems, research laser platforms and other precision deep-ultraviolet optical applications, providing stable, high-performance beam modulation for 257–266 nm laser systems.
