High-Performance Acousto-Optic Tunable Filters (AOTF)
CASTECH’s AOTFs are solid-state, electronically addressable, and offer random-access optical bandpass filtering. These filters utilize TeO2 slow shear waves to provide optimal performance across a wide wavelength range. Key features include:

• Wide Wavelength Range: Operates from 400 nm to 1450 nm, ideal for various applications.
• Resolution: Achieves a fine resolution as low as 3 nm, ensuring precise wavelength selection.
• Large Aperture: Effective aperture of up to 10 mm for increased performance.
• Non-Collinear Structure: The filter’s design allows for diffraction of two orthogonal polarizations of light.
• Easy Integration: Can be fiber-coupled for easy setup in different systems.

Applications:

• Spectral Polarization: Fine-tune light polarization for precise control in experiments.
• Hyperspectral Imaging: Enable detailed spectral analysis across wide wavelength ranges.
• Wavelength Selection: Dynamically select specific wavelengths from a broad spectrum.
• Optical Communication: Ensure accurate wavelength management for optical communication systems.
• Laser Wavelength Tuning: Adjust laser wavelengths for various applications.

Optimized Performance: For the best performance, CASTECH recommends using RF drivers, available in fixed-frequency and variable-frequency series, for smooth and reliable operation.

CASTECH’s AOTFs are fully customizable to meet specific customer requirements and are produced with the highest quality standards.
