Medium & Low Power Optical Isolator
Free-space isolators are based on Faraday rotators with the addition of polarization elements, preventing laser light from returning along its original path. Pulse Optics Isolators utilize common magneto-optical materials such as YIG, TGG, and CeF3, with wavelength coverage ranging from 266nm to 4500nm, and the maximum aperture available is 25mm. Custom wavelengths are also available.
