Product description

The AOMO 3110-191 provides controlled modulation for near-infrared laser systems where predictable beam behaviour and stable optical performance are required. Its tellurium dioxide acousto-optic material supports efficient beam interaction, helping deliver reliable modulation in precision laser and photonics platforms.

This modulator is well suited to systems where the undiffracted beam remains an important part of the optical design. Its rectangular aperture supports controlled beam handling, while low reflectivity, high contrast switching and special testing provisions help support clean beam control in optical test platforms, scientific laser systems, laboratory photonics and OEM instrumentation.

  • Example AR Coating Curve (Guidance only)

    AR coating curve chart titled “1064 nm V-coat Calculated Reflectance vs. Wavelength,” showing reflectance per surface plotted against wavelength from 800 to 1400 nanometres. The single blue curve falls from about 2.2% at 800 nm to a minimum close to 0% near 1064 nm, then rises steadily again to about 2.4% by 1400 nm, indicating the coating’s optimum antireflection performance at approximately 1064 nm.
