Ultra narrow line broadband fiber Bragg grating FBG filter 1539.4/1551.08nm (bandwidth<0.05nm, reflectivity 90% polarization maintaining optional)

Xiaoxiao Photon's ultra narrow linewidth passband filter is based on our advanced fiber Bragg grating technology. Narrow linewidth passband filters can be used to select small bandwidth optical signals to pass through and block all other wavelengths. This narrow linewidth passband filter is designed for applications such as fiber laser ASE noise suppression, laser radar filters, high-resolution Raman spectroscopy, fluorescence microscopy, and optical instruments.
