2 Micron Fiber Isolator
Polarization Insensitive: AP-ISO-2000PI
Polarization Maintaining: AP-ISO-2000PM
An isolator is typically used to block light traveling in the backward direction, preventing instability
and damage to a laser system caused by back reflection.

Features:•••••

Mid-IR wavelength region
Low insertion loss
High isolation
Excellent stability and reliability
Small package
