1064nm SM Isolator

1064nm SM Isolator

This single-stage single-mode optical isolator for 1064 nm provides high isolation and low insertion loss, ensuring reliable protection for laser sources against back reflections. Designed with low polarization-dependent loss and high return loss, it offers stable performance in a compact package.

Ideal for high-power laser systems, fiber amplifiers, and precision optical instrumentation, the isolator maintains consistent operation across specified temperature ranges. Custom configurations including fiber type, connector options, and fiber length are available to meet specific integration requirements.
