Description
780nm PM Tunable Optical Filter
780nm PM Tunable Optical Filter is a fiber passive component which can be used for filter out variable wavelength range from a wide wavelength bandwidth, it’s based on thin film cavity filter technology, the demanded wavelength can be filtered out precisely by adjusting the manual screw. Wavelength can be tuned continuously over a wide spectral range up to 20nm, it’s widely used in Fiber Optic Sensor and Optical Comb System. High power type is available upon request.
