Product description

The AOMO 3200-1913 provides high-speed modulation for compact infrared laser systems where rapid beam gating, optical switching and intensity control are required. Its tellurium dioxide acousto-optic material supports efficient beam interaction, helping deliver reliable performance in small-beam photonics assemblies.

This modulator is well suited to telecom-wavelength optical systems where fast response, compact beam handling and defined separation between diffracted and undiffracted beams are important for integration. Low reflectivity, high contrast switching and compact RF compatibility support clean, repeatable performance in optical test platforms, telecom photonics, laboratory systems and OEM instrumentation.

  • Example AR Coating Curve (Guidance only)

    AR coating curve chart titled “V-Coat at 1550 nm,” showing reflection percentage plotted against wavelength from 1200 to 1900 nanometres. The single blue curve forms a broad U-shape, starting near 2.0% at 1200 nm, falling to a minimum of about 0.1% around 1550 nm, and then rising again to roughly 1.3 to 1.4% by 1900 nm, indicating optimum antireflection performance at approximately 1550 nm.
