Product description

The AOMO 3080-122 provides controlled modulation for red and near-infrared laser systems where reliable beam gating, optical switching and intensity control are required. Its tellurium dioxide acousto-optic material supports efficient beam interaction, helping deliver stable performance in compact photonics platforms.

This modulator is well suited to systems where engineers need to balance switching response, modulation bandwidth and diffraction efficiency through beam-size selection. Low insertion loss, low reflectivity, high contrast switching and wavelength-matched coating performance help support clean beam control in optical test platforms, laboratory photonics, imaging, sensing and scientific laser systems.

  • 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.
