1539.4nm Narrow Bandwidth Fiber Bragg Grating (FBG) Filter (Bandwidth < 0.05nm, reflectivity up to 90%, polarization-maintaining optional)

This narrow bandwidth bandpass filter from IdealPhotonics is based on our advanced Fiber Bragg Grating (FBG) technology. The narrow bandwidth bandpass filter can selectively transmit light signals with a small bandwidth while blocking all other wavelengths. This 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
