Product description
The AOMO 3120-193 provides controlled modulation for compact near-infrared laser systems where responsive switching, stable beam handling and reliable intensity control are important. Its tellurium dioxide acousto-optic material supports efficient beam interaction, helping deliver dependable performance in space-conscious photonics assemblies.
This modulator is well suited to systems where compact beam paths and fast optical response are more important than larger-aperture beam handling. Low reflectivity, high contrast switching and fixed-polarization operation support clean beam control in optical test platforms, scientific laser systems, laboratory photonics and OEM instrumentation.
