Paper Abstract

Spectrophotometric measurements are used in a great number of industrial processes (chemical, pharmaceutical, farm-produce...) in nuclear environment and with optical precision components. Especially the evolution of a chemical process or of an optical coating could be followed by these measurements. Spectrophotometers, using optical fibers to transport the signal out of the instrument make possible the measurement "in-situ" and in real time. The advantage of using a diode array to detect the signal is an instantaneous measurement all over the spectral range without moving parts. It allows an excellent reproductibility of the measurements. The instrument is controlled by a micro computer. The spectrophotometer will be described and its technical performs presented. An extension using optical fibers on a "classical" spectrophotometer (a H.P. one) will be also described and its technical performs with such a system presented.
