Product description
The G&H AOTF PCAOM 500–850 nm is an acousto-optic tunable filter designed for fast, precise wavelength selection and multi-wavelength optical control across the 500–850 nm spectral range.
Using a TeO₂ acousto-optic medium, it combines high diffraction efficiency and low optical loss with rapid wavelength access and simultaneous multi-frequency operation. Its broad spectral coverage makes it particularly suited to laser systems, fluorescence imaging, spectroscopy, spectral imaging and scientific instrumentation requiring flexible control across visible and near-infrared wavelengths.
