Overview
The Luna NISO is the NoTail version of the In-line Isolator (ISO & NISO) from the former General Photonics passive component line. An isolator transmits light only in the forward direction. The NISO is available as a polarization-insensitive single-mode (SM) or a polarization-maintaining (PM) isolator, in single-stage or double-stage configurations.
The NoTail package has no external fiber pigtails, which avoids the problems pigtails can cause. Its short optical path suits ultra-short pulse and interferometric applications. NoTail versions are also easy to use in the laboratory and easy to store.
The isolators are compact and built to work reliably in a wide range of environments. Their small size, low loss and low back reflection make them suitable for integration into fiber optic systems. The NoTail version is offered for the 1310 nm and 1550 nm wavelengths. Luna lists this product as discontinued.
