Dynamic Tunable Bandpass Filters
Brimrose’s Dynamic Tunable Bandpass Filter adjusts the center wavelength of a narrow band of light over a 100-200nm tuning range. It offers very high resolution (~1.5 nm) and can select single or multiple wavelengths simultaneously. It is able to precisely and rapidly adjust the wavelength and intensity of the diffracted/filtered light by varying the RF frequency and power.
Available in free-space and fiber-coupled configurations, the dynamic tunable filter provides high-resolution wavelength selection for a wide range of optical systems, including spectroscopy, sensing, imaging, telecommunications, and industrial monitoring applications across multiple wavelength ranges.
Performance Capabilities
Dynamic tunable bandpass filters deliver high-performance wavelength selection through precise ao control, enabling rapid tuning, high spectral resolution, and dynamic intensity adjustment. They support a wide range of optical and photonic applications with customizable solutions for flexible, accurate wavelength management.
