The most reflective mirrors of the world are at the LMA laboratory (Laboratoire des Matériaux Avancés/laboratory of advanced materials) in Lyon. Up to two years is needed to integrate gravitational wave detectors like LIGO or VIGO. As key elements in these detectors, they are among the most accurate optical components ever produced in the world. Each of their processing steps must be conducted under stringent temperature, hygrometry and cleanliness conditions to reach the most perfect end-result as possible.
