Product description：
Acousto-optic tunable filters(AOTF) are used to pick and transmit a specific wavelength from a broadband or a multiline laser source efficiently. The transmitted wavelength of the narrow passband changes as the RF driver frequency changes. Compared with other types of filters, the primary advantage of acousto-optic tunable filters is its fast tuning speed. Wavelength tuning can be accomplished in tens of microseconds.
CATECH's acousto-optic tunable filters are fabricated using high quality TeO2 crystals grown in-house. The products are suitable for a wide variety of wavelengths.
Applications：
●Laser wavelength tuning
●Wavelength selection
●Laser-microscope
●Laser imaging
●Spectroscopy
