This Product Selection Guide contains information to help select products in the Faraday Isolators category on DigiKey.com
Faraday Isolators are used in laser optic systems to transmit light in one direction while blocking it in the opposite direction. These can be filtered by wavelength, aperture, maximum beam diameter, isolation, polarizer, and more.
SelectionCharacteristics
Wavelength: Indicates the wavelength(s) the device is designed to isolate.
Aperture: The size of the opening through which the laser beam passes within the isolator.
Maximum Beam Diameter: Indicates the maximum diameter of the laser beam that can be isolated by the device.
Isolation: A measure of the difference in power applied to a device’s input port and the portion thereof that appears at its isolated port, when properly terminated.
Transmission: The percentage of incident laser power that passes through the isolator without being absorbed or attenuated.
Polarizer: The type of optical component used to control the polarization of the laser beam within the isolator.
