1064nm PM Fiber Bandpass Filter, 3nm Passband

Overview

The FT-1064-57 is a 1064 nm polarization-maintaining fiber bandpass filter built around a 3 nm pass window. It selects the wanted spectral slice near 1064 nm while the stop band attenuates neighboring light by 25 dB, reducing cross-channel interference in dense fiber layouts. The 3 nm bandwidth balances noise rejection with alignment tolerance, which helps in field-deployed assemblies where center wavelength may drift slightly. Insertion loss is measured over center wavelength ±2.5 nm, keeping in-band loss flat across the window. The PM fiber pigtails preserve polarization through the filter, and stop-band, extinction and return-loss targets are listed in the specification table.
