  • Ultraviolet-Visible Spectrometry Characterization of
    Small, portable ultraviolet and visible spectrometers can be used to characterize the combustion and. regression rates of hybrid rocket and other combustion emission plumes. In this study, two spectrometers,. operating in the ultraviolet and visible ranges, were used to measure the hydroxyl radical

    in photosensitive resist material, relies on deep-ultraviolet (DUV) steppers and scanners to achieve linewidth reductions. In turn, these new-generation tools derive their light from a type of gas laser known as excimer (short for ), which uses fluorine and rare-gas mixtures to produce wavelengths
