1551.08nm Narrow Linewidth Fiber Bragg Grating (FBG) Filter (Bandwidth < 0.05nm, Reflectivity up to 90%, PM Option Available)

IdealPhotonics' narrow linewidth passband filter is based on our advanced fiber Bragg grating technology. The narrow linewidth passband filter can be used to select narrow-bandwidth optical signals to pass through while blocking all other wavelengths. This narrow linewidth passband filter is designed for applications such as fiber laser ASE noise suppression, lidar filters, high-resolution Raman spectroscopy, fluorescence microscopy, and optical instruments.

Product features：Ultra-narrow bandwidth、 All-fiber structure、 Wavelength selectable、 Wide stopband width、 Different fiber types available

Application area：Fiber laser noise filtering、 Lidar spectral noise filtering、 High-resolution Raman spectroscopy analysis、 Fluorescence imaging
