Acousto-Optic Tunable Filters (AOTF) for Precise Wavelength Selection

CASTECH’s acousto-optic tunable filters (AOTFs) provide highly accurate and fast wavelength selection, offering a wide range of applications from spectral analysis to optical communications. These solid-state, electronically addressable filters enable dynamic, real-time tuning of optical wavelengths with precision and speed. Key features include:

  • Wide Wavelength Range: Operating from 400 to 1450 nm, suitable for diverse optical applications.
  • High Resolution: Achieves a resolution as fine as 3 nm, enabling precise wavelength selection.
  • Effective Aperture: Supports apertures up to 10 mm, accommodating different light beam sizes.
  • Non-Collinear Structure: The AOTF design supports diffraction of light with orthogonal polarization, ensuring optimal performance across a broad range of wavelengths.
  • Fiber-Coupling Ready: Designed for easy integration into systems, with fiber-coupling options for added flexibility.
  • Optimized RF Drivers: For best performance, CASTECH recommends using our RF drivers, available in both fixed-frequency and variable-frequency options.

Applications:

  • Spectral Polarization: Used for precise polarization control in optical systems.
  • Hyperspectral Imaging: Ideal for wavelength selection in hyperspectral imaging systems.
  • Wavelength Selection: Quickly and accurately selects specific wavelengths from a broad spectrum.
  • Optical Communication: Facilitates dynamic wavelength tuning for optical communication systems.
  • Laser Wavelength Tuning: Essential for tuning laser outputs in various research and industrial applications.

CASTECH’s AOTFs are engineered for reliability and performance, providing tailored solutions that meet the needs of professionals across multiple industries. Customization options are available to fit specific application requirements.
