Product description

The AOMO 3200-124 provides controlled modulation for red and near-infrared laser systems where compact beam handling, responsive switching and reliable intensity control are required. Its tellurium dioxide acousto-optic material supports efficient beam interaction, helping deliver stable performance in precision photonics assemblies.

This modulator is well suited to systems using small, controlled beam diameters where fast optical response and compact optical layout are more important than larger-aperture beam handling. Low insertion loss, high contrast switching, beam quality specification and burn-in tested operation help support dependable performance in optical sensing, imaging, instrumentation, laboratory photonics and scientific laser platforms.

  • Example AR Coating Curve (Guidance only)

    AR coating curve chart titled “830 nm V-Coat on <110> TeO2,” showing percent transmission (%T) plotted against wavelength from 700 to 1100 nanometres. The single magenta curve starts at about 1.5% near 700 nm, falls steadily to a minimum of roughly 0.08% around 830 to 835 nm, and then rises again, reaching about 2.0% by 1100 nm. The curve illustrates optimum coating performance near 830 nm.
