Acousto-Optic Tunable Filters
Acousto-optic tunable filters are used to select and ransmit a specific wavelength from a broadband or a multi line laser source dynamically. The transmitted wavelength of the narrow passband changes as the RF drive frequency changes.
Compared with other types of filters, the primary advantage of acousto-optic tunable filters is that the tuning speed is fast. Wavelength tuning can be accomplished in tens of microseconds.
CASTECH's acousto-optic tunable filters are fabricated using high quality TeO 2 crystals grown in-house . The products are suitable for a wide variety of wavelengths .
