SKU: FOTF
Based on our proprietary thin film cavity filter technology, we manufacture Fiber Optic Tunable Filters with central wavelengths ranging from 750nm to 2450nm. These filters are continuously tunable over a wide spectral range of up to 100nm, with a peak bandwidth of 3nm. Longer center wavelengths offer a larger tuning range. The tuning mechanism involves manually rotating a mirror using a precise micrometer. The filters feature low insertion loss, making them a preferred solution for OEM applications ranging from fiber optic networks to fiber sensing interrogation. Our standard configurations are currently in volume production, providing a low-cost benefit. Customization for other wavelengths is available at an additional cost.
These grating-based tunable filters block the off-bands.
