Where to Buy Faraday Isolators

Faraday isolators are essentially optical one-way devices, largely blocking radiation in one direction. They can be used, for example, for protecting lasers and laser amplifiers against optical feedback. There are bulk devices as well as fiber-coupled isolators, some of which are polarization-sensitive.

Faraday isolators

Edmund Optics free-space optical isolators incorporate a Faraday rotator and are specifically designed and manufactured to provide superior performance with high isolation, transmission, and power densities. Each option effectively reduces feedback in the external cavity of diode laser systems and blocks reflections from free-space fiber coupling. These isolators enable state of the art protection for the most stable lasers in the world and are ideal for demanding laser applications.
