Dynamic Tunable Bandpass Filters
The Dynamic Tunable Bandpass Filter adjusts the center wavelength of a narrow band of light over a 100 - 200nm range. It offers very high resolution of ~1.5nm and either single or simultaneous multiple wavelength selection. It is able to precisely and rapidly adjust the wavelength and intensity of the diffracted/filtered light by varying the frequency and RF power.
Brimrose offers both free-space and fiber-coupled configurations. AOTFs are used widely in numerous optical systems and applications, especially in industrial or process control near-infrared (NIR) spectroscopy applications.
