Polarization-maintaining Fiber Optics

A stable measurement setup is fundamental for any successful measurement. A major cause of frustration and error is the need to continuously readjust optomechanical equipment because of continuous instabilities. The use of fiber optics has proven to increase both stability and convenience significantly when compared with standard free-beam setups. These modular, complex and self-contained setups also often increase laser safety and reduce the laser safety classification. The defined interface between a laser source and the more sensitive environment of the measurement setup provides the physical separation that enables a mechanical and thermal decoupling, suppressing mutually negative effects.
