Tunable Filters (AOTF)

An Acousto-Optic tunable filter is a pass-band transmission filter, which exploits the acousto-optic interaction inside an anisotropic medium. AO tunable flters are generally fabricated in Tellurium Dioxide, operating within the visible to near/mid infra-red. The AO tunable filter allows the user to select and transmit a single wavelength, or in some cases a selection of multiple discrete wavelengths from the incoming light. The center of the pass-band may be selected simply by tuning the drive frequency.
Over a number of years G&H has maintained an ambitious development program which we beleive has enabled us to enhance the general performance and increase the capabilities of AOTF technology. Our product range includes purpose designed solutions for illumination / excitation wavelength selection and multispectral / hyperspectral imaging, for which we also offer the latest DFS driver technology.
Typical applications include: Biomedical (confocal microscopy & hyperspectral imaging), Scientific (spectroscopy) and industrial (process control). For more information on how to select an AOTF please read our Buyers Guide.
