Acousto-optic tunable filters (AOTFs) are solid state wavelength tunable optical filters. Interactions of photons with these perturbations allow the AOTF to selectively diffract a single narrow-bandpass wavelength. The wavelength may be varied by changing the applied frequency.
Acousto-optic tunable filters (AOTF) are used to rapidly and dynamically select a specific wavelength from a broadband or multi-line laser source. As the applied RF frequency is varied, the transmitted wavelength changes, “tuning” the wavelength of the beam or image in tens of microseconds or less.
AOTF Acousto-optic Tunable Filter 430-1450nm AOTF-Pro
The AOTF-Pro acousto-optic tunable filter system is the latest generation of optical splitting modules. It can realize the switching output of supercontinuum light source and single wavelength. The single-wavelength output range of AOTF-Pro covers an ultra-wide band of 430nm-1450nm, which can achieve the largest range of single-wavelength options within a single spot, fully covering the required range of nanophotonics, fluorescence spectroscopy research and other fields. The AOTF-Pro splitter module can also use single-mode fiber for direct output, and it can be seamlessly connected to analysis systems with single-mode fiber output devices such as confocal microscopes and spectrometers.

AOTF RF DRIVERS FOR ACOUSTO OPTIC TUNABLE FILTERS
ERZIA designs and manufactures RF Drivers for space-based acousto optic tunable filters (AOTF) and acousto-optic modulators (AOM). The limited energy available in space platforms, along with the demand for reliability, RF output power, and linearity requires a dedicated and specific approach to the design and implementation of these modules. ERZIA has several design approaches that allow a fast and efficient implementation of these modules for space applications, which can include not only the RF amplifier, but also additional features like housekeeping signals, variable gain, or special impedance matching.
