Based on a proprietary thin film cavity filter technology, we produce Fiber Optic Tunable Filters with central wavelengths of 1060nm to 2050nm having a long tuning range over 120nm. Other center wavelength can also be made. This is achieved by combining two tunable filters and two wavelength independent optical switches. The wavelength tuning is made by manually rotating two precise micrometers; one at a time and selected by a push button toggle switch. Our unique low insertion loss design presents a cost-effective solution for long range fiber tunable filter.
