摘要

Equipment of the transmission and distribution of application by optical fibers, in particular for the control spectrophotometric in line with the aid of a spectrophotometer 1 double beam, namely a channel for the reference r and a channel for the measurement m / p & & p & it comprises at least one light source 12 emitting complementary through a network of optical fibers 24, 25 permanently to a reference cell 23, and sequentially, towards one of the n measurement cells 19 corresponding to the controles to carry out, the light coming from the reference cell 23 on the one hand, and sequentially, each of the measurement cells 19 on the other hand, since fwd by the network of optical fibers, respectively, to the reference 2 and to the measurement channel 3 of the spectrophotometer 1.
