Near-Infrared Acousto-Optic Modulator AOMO 3120-193
AOMO 3120-193 is a compact near-infrared acousto-optic modulator using tellurium dioxide as the acousto-optic medium. Designed for precision near-infrared laser systems, it provides high-speed optical switching, stable beam modulation and precise intensity adjustment. Optimized for small beams, it combines fast response, high switching contrast and excellent optical stability to meet modulation-accuracy and reliability requirements in space-constrained photonic systems. The excellent acousto-optic properties of TeO₂ allow AOMO 3120-193 to provide efficient, stable beam interaction and precise beam control while maintaining good beam quality. Low reflectance, fixed-polarization operation and compact construction facilitate integration into high-performance optical platforms and maintain stable modulation during long-term operation. Applications include optical test platforms, research laser systems, laboratory photonics equipment, OEM optical instruments and other precision near-infrared laser applications, providing reliable modulation for systems requiring fast response, high stability and precise beam control.
