Isomet’s electronically controlled acousto-optic filters (AOTF) are specially designed for use with broadband light sources and are often used with non-coherent and divergent light.
Tunable AOTFs make use of the inherent dependence of wavelength sensitivity in relation to so-called Bragg diffraction and thus enable specific wavelengths of broadband light sources to be filtered out by applying different radio frequencies (RF). Corresponding RF drivers are also available.
Range features
A high level overview of what this range offers
- Wavelength range: VIS, NIR, and mid-IR

- Acceptance angle of 2.5° up to 6°
- Low input angular sensitivity
- High wavelength selectivity
- Intensity modulation through the level of HF power
- Suitable synthesisers also with an integrated amplifier
