Description
Our Large Aperture free space isolators are available in a wide variety of wavelengths and can be purchased factory-tuned to a particular wavelength or user-tunable. These isolators offer high isolation with a choice of low, medium and high power capability. Any of these units can also be purchased without polarizers as a Faraday Rotator. |
