art photonics’ Aluminum Coated Silica Fibers (Brand Name FlexiRay® MCS-A) are the optimal solution for the use under harsh environmental conditions, i.e. high temperature, vacuum, or corrosive chemicals. In addition to all the benefits of silica-silica fibers, hermetically sealed FlexiRay® MCS-A possess increased mechanical strength and greater fatigue resistance. Important, transmission of FlexiRay® MCS-A covers a spectral range of 200 to 2400 nm depending on the chosen UV- or NIR-silica fiber core.
