1064nm Polarization Maintaining Filter WDM

Overview

The FT-1064-19 is a polarization-maintaining filter wavelength division multiplexer that separates or combines the 1064 nm and 980 nm channels in one compact package. The transmission channel carries 1064 nm with maximum insertion loss of 0.8 dB, while the reflection channel handles 980 nm at 0.6 dB maximum loss. Channel flatness is held to 0.4 dB, and minimum isolation reaches 25 dB for the transmission path and 15 dB for the reflection path. With a minimum extinction ratio of 18 dB at 23 ℃, the device suits pump-signal coupling in fiber laser and amplifier chains. Fiber type, package and connector options follow the specification and ordering tables.
