Green-Light Acousto-Optic Modulator AOMO 3250-220
AOMO 3250-220 is a compact green-light acousto-optic modulator using a quartz-crystal acousto-optic medium. Designed for small-beam green laser systems, it provides high-speed optical switching, beam gating, pulse picking and dynamic intensity modulation. Fast response, stable modulation and compact construction meet beam-control accuracy, timing-consistency and system-integration requirements in precision laser systems. The excellent optical properties and stable acousto-optic interaction of crystalline quartz allow AOMO 3250-220 to modulate green laser beams efficiently and precisely, providing reliable beam-delivery control, optical-power adjustment and precise timing management while maintaining good beam quality. Its miniature design is particularly suitable for space-constrained optical platforms, providing long-term stable operation for small-beam laser applications. Applications include laser-scanning microscopy, fluorescence excitation systems, analytical and inspection instruments, laser-scanning equipment, research experimental platforms and laboratory photonic systems, providing high-performance, highly reliable beam modulation and control for green-laser applications.
