Free-Space Optical Isolator and Faraday Rotator Product Line

Product Description

Our free-space optical isolator (Faraday isolator) and Faraday rotator selection includes a wide range of wavelengths, with typical isolation as high as 40 dB for single stage, and 75 dB for dual stage units. Various models can be purchased with fixed-wavelength, or with user-friendly tunability. We also offer a broadband optical isolator selection for applications such as Ti: sapphire lasers where instantaneous broadband operation is required. Most of our optical isolators are available with a choice of low, medium or high power capability.
