Lines of instrumentation: Visible instrumentation

Visible instrumentation

From its origins, the Instrumentation Division has participated in the construction of instrumentation to detect and analyze light in the visible range of the spectrum. Cameras, spectrographs, polarization analyzers, optical fibers fed systems, among others, have been designed, built, integrated and verified in our facilities.
