Product details
Overview
The FT-1064-71 combines an optical isolator with a bandpass filter in one Faraday-based package for 1064 nm systems. The isolator stage blocks reflected light from traveling back toward the source, protecting upstream components such as laser diodes and amplifiers. The bandpass stage passes the target spectral band around 1064 nm while rejecting out-of-band energy. Integrating both functions into a single device saves space in compact fiber optical layouts. It suits fiber laser assemblies, optical test instruments, fiber sensors and EDFA systems.
