1064nm PM Fiber Bandpass Filter, 2nm Passband

Overview

The FT-1064-58 is a 1064 nm polarization-maintaining fiber bandpass filter with a 2 nm passband. It passes the target 1064 nm band while rejecting out-of-band light by at least 25 dB in the stop band, cleaning up broadband noise and unwanted spectral lines before detection. The narrow 2 nm window fits applications that need tight spectral selection, such as seeded laser cleanup and ASE suppression in PM amplifier chains. The PM fiber construction preserves polarization state through the filter, and the design targets low in-band insertion loss and high return loss across the operating temperature range.
