For the calibration of your reference materials, LNE features ultraviolet measurement equipment extending through the medium infrared spectrum, with uncertainty values at the very best levels. As the driver of French metrology practices, LNE's calibration chain and methods deployed are synchronized with the International System of Units (SI).
