532nm 1x2 Polarization Beam Combiner/Splitter
Firsol 532nm 1x2 Polarization Beam Combiner/Splitter is a passive fiber optic component designed to split a single optical signal into two orthogonally polarized outputs or combine two orthogonally polarized input signals into one output fiber. Operating at a center wavelength of 532nm with a ±10nm operating wavelength range, it provides insertion loss of ≤1.5dB, an extinction ratio of ≥18dB, return loss of ≥50dB, directivity of ≥50dB, and maximum CW optical power handling of 0.1W. Ports 1 and 2 use polarization-maintaining fiber, while Port 3 can be configured with single-mode fiber or an all-PM fiber structure. Its stable polarization performance and reliable construction make it suitable for visible-light fiber lasers, optical sensing, laboratory research, polarization analysis, and other polarization-maintaining fiber systems.
