NISO – NoTail Isolator
DESCRIPTION
General Photonics' NoTail™ isolators are available in both polarization independent versions (SM fiber) and polarization maintaining versions (PM fiber). All models pass light forward with minimal loss while isolating systems from light travelling in the opposite direction. With double stage isolation, up to 52 dB of isolation is possible. The short optical path of about 7 cm supports ultra-short pulse and interferometric applications. General Photonics also offers pigtailed isolators (ISO family)
