Product description
The G&H AOTF PCAOM VIS 400–650 is a visible-range acousto-optic tunable filter designed for precise wavelength selection and multi-wavelength optical control across 400–650 nm. Using a TeO₂ acousto-optic medium, it combines high diffraction efficiency with low optical loss and stable wavelength performance, making it well suited to demanding scientific, biomedical and analytical optical systems.
Its ability to control multiple wavelengths through a single acousto-optic device provides a flexible alternative to conventional mechanical wavelength-selection techniques, supporting compact and responsive optical system designs.
