Tunable optical filter applicable to fiber-optic communication, sensing, medical and biological analysis.

FBPF, Wavelength tunable fiber-optic filter module

FBPF is a fiber-optic module including the small pedestal on which the optical filter is mounted.  The customers can easily change the center wavelength of the optical filter by turning the pedestal.  This module is suitable for the noise reduction filter module built in the equipments of the optical communication or the fiber-optic sensing.
