An Acousto-Optic tunable filter (AOTF) is a pass-band transmission filter, which exploits the acousto-optic interaction inside an anisotropic medium. AOTF is generally fabricated in Tellurium Dioxide, operating within the visible to near/mid infra-red.
This AOTF system is simply a plug and play module with any of the YSL supercontinuum system. For each integrated AOTF crystal, the system enables up to 8 simultaneous tunable wavelength channels. Combines of three different crystals, the AOTF module covers the entire supercontinuum spectrum from 400nm to 2400nm. The system can be equipped with either one or two of them according to customer demand. The AOTF offers a free-space collimated beam as standard optical output. As an alternative, a single-mode fiber delivered output is also available.
AOTFs are used for high resolution microscopy, fluorescence microscopy, nanophotonics, and material characterization.
