Optical Isolators for Lasers
Conoptics manufactures a family of modular Faraday rotators and interchangeable accessories which can be combined to perform various isolation functions.
700 Series Faraday Rotator and Accessories
The unique feature of a Faraday rotator is its nonreciprocity, that is, the fact that the “handedness” of the polarization rotation it imparts on a transmitted beam is dependent on the beam’s propagation direction. By far the most common application of Faraday rotators is their use in optical isolators, devices used to protect laser sources from harmful back reflections.
