Crylink's Faraday isolators are optical components commonly used in precision laser systems. A Faraday magneto-optic isolator allows laser light to travel through an optical path in only one direction. It protects the laser emission system against light reflected from other optical components. Such reflections can cause unstable output in energy, noise, mode and linewidth, and, in the most severe cases, permanent damage to optical components. The isolator manual explains how a Faraday isolator works. Crylink offers fixed-wavelength UV, visible and near-infrared isolators covering 480nm-1064nm. At the preset center wavelength, these Faraday isolators can provide transmittance of at least 90% and isolation greater than 30dB. Crylink's dual-stage isolators are available when higher isolation is required. Crylink also offers Faraday rotators, allowing selection according to the application.
