Fibre Based Narrow Linewidth Pass-band Filter
This fibre based narrow linewidth passband filter, with model number OEPBF-100, offers a narrow linewidth passband and a wide blocking band. The narrow linewidth passband filtre can be used to select a small bandwidth optical signal to pass and block all other wavelengths. This narrow linewidth pass-band filter is intended to use in applications such as fiber laser ASE noise suppression, laser radar filter, high resolution Raman spectroscopy, fluorescence microscopy and optical instrumentation.
Features:
- Fibre based device
- Ultra narrow bandwidth
