The OITG Series Free Space optical Isolator is an unidirectional light valve that transmits light in normal direction while blocking backreflection and backscattering in the reverse direction. The device protects a laser source from destabilizing feedback or damage from back reflected light. The OITG isolators are based on TGG Faraday crystals of low loss and high optical power threshold. High power fused silica PBS cubes are used for polarization filtering and waveplate is optional to rotate the polarization of the output beam to a desired direction. Double escape ports are built-in for added application flexibility.
