Optical Isolators

Optical isolators are devices that allow the transmission of laser beams emitted from a laser diode to travel in only one direction. When built into the laser modules which form the light sources for optical communications, optical fiber amplifiers, and other components, they protect the laser diode by intercepting light reflected back from the optical fiber conductors. Our optical isolators can also be used for laser processing machine heads and that contributes to the processing quality. We manufacture the Faraday rotators that are the material for optical isolators and the prosess is environmentally friendly because it eliminates lead that is restricted in RoHS Directive.
