1539.4nm Narrow Bandwidth Fiber Bragg Grating (FBG) Filter

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
