... steel grating is imported as a specifically fabricated component of a finished product such as pipe rack, stair tower or process module. In this case, the steel grating would have been manufactured to fit each particular structure and cut to the required sizes and shape, and had banding, collar plates or other mild steel material added to it.  3, fiche 1, Anglais, - banding

Ultra High Resolution Spectrometer(UHRS).... Laser spectroscopy has stimulated the development of spectrometers with improved performance and has led SOPRA to develop a new line of monochromators with ultra-high resolution. SOPRA has designed the mechanical parts in the most careful way to take the best advantage of the newest diffraction gratings. The instrument function of a monochromator is defined by the product : Resolution X Luminosity/Noise=RL/N. The resolution R directly depends on the diffraction grating and the focal length. The luminosity L depends on the area, on the efficiency of the grating, and on the slits. The noise N is essentially caused by the light scattered by the grating through the output slit and it diminishes when the focal length is increased. Another crucial quality factor of a monochromator is the ease to use it, i. e. its stability and reproducibility with regard to resolution and luminosity, and its tuning characteristics.  1, fiche 3, Anglais, - ultra%20high%20resolution%20spectrometer
