The FOTF-EM series motor-driven optical tunable filters are highly versatile, supporting free-space, multimode, and single-mode operation, unlike traditional etalon- or grating-based tunable filters that typically work only with single-mode fiber. Based on a proprietary edge-filter platform, these filters are available with center wavelengths ranging from 350 nm to 2450 nm. They provide continuous wavelength tuning over ranges up to 100 nm with an approximate 5 nm linewidth. Wavelength tuning is performed by a built-in precision stepper motor, controlled through USB or RS232 interfaces. The design offers high reliability, low insertion loss, and cost-effective performance, making it suitable for a wide range of applications. Standard wavelength configurations are produced in volume to ensure cost efficiency, while custom wavelengths are available at additional cost. The thin-film filter structure also incorporates blocking layers to suppress off-band transmission, ensuring improved spectral performance.
Agiltron’s Manual Grating-Based Fiber Optic Tunable Filter provides a simple way to adjust the center wavelength of a narrow band over a wide band. Wavelength tuning is achieved by rotating a grating using a micrometer.
Based on proprietary optics, Agiltron offers extremely low insertion loss, high stability, polarization-independent operation, and high off-band suppression. It is tunable continuously over a wide spectral range. The device presents a most cost-effective solution for OEM applications from fiber optic networks to fiber sensing interrogation.
This series of Electrically Tunable Grating-Based Fiber Optic Tunable Filters offers an exceptionally wide tuning range of over 150 nm, low insertion loss (~1.5 dB), and a narrow linewidth of 0.7 to 1.0 nm. The tunable passing band features a Gaussian-shaped peak and is continuously adjustable across a wide spectral range via a grating rotated by a micro-step motor. Wavelength tuning is controlled through a USB or RS232 interface with a GUI, and a 5V DC power supply is included. Utilizing proprietary optics, Agiltron ensures high repeatability, with options for polarization-independent or polarization-dependent operation and strong off-band suppression.
