Product description

The AOMO 3200-121 provides controlled modulation for visible and near-infrared laser systems where compact beam handling, responsive switching and stable intensity control are required. Its tellurium dioxide acousto-optic material supports efficient beam interaction across a broad optical range, helping deliver reliable performance in precision photonics assemblies.

This modulator is well suited to systems using small, controlled beam diameters where engineers need to balance switching speed, optical efficiency and beam quality. Broadband anti-reflection coated optics, high contrast switching and an SMB-flanged format support clean integration into microscopy, imaging, analytical instrumentation, optical test platforms and laboratory photonics systems.

  • Example AR Coating Curve (Guidance only)

    AR coating curve chart titled “440–850 nm BBAR on <110> TeO2,” showing reflection percentage plotted against wavelength from 400 to 850 nanometres. The single curve begins at about 4.5% reflectance near 400 nm, falls steeply to below 1% by roughly 445–450 nm, then remains low and relatively flat across most of the broadband range. It reaches its lowest point at around 720 nm at approximately 0.25% reflectance before rising gradually again toward about 0.9% at 850 nm, illustrating broadband antireflection performance across the visible and near-infrared range.
