Ultraviolet–visible spectroscopy single-beam instrument, the cuvette containing only a solvent has to be measured first. Mettler Toledo developed a single beam array spectrophotometer that allows fast and accurate measurements over the UV/VIS range. The light source consists of a Xenon flash lamp for the ultraviolet (UV) as well as for the visible (VIS) and near-infrared wavelength regions covering a spectral range from 190 up to 1100 nm. The lamp flashes are focused on a glass fiber which drives the beam of light onto a cuvette containing the sample solution. The beam passes through the sample and specific wavelengths are absorbed by the
Ultraviolet (Light My Way) singing the repeated "baby"s, one of the most heavily used clichés in pop songs and one that he had avoided up to that point in his songwriting; Flood later commented that "he got away with it alright." Although the song is ostensibly about love and dependency, like many U2 songs, it also lends itself to religious interpretations. Listeners have heard an allusion to the Book of Job and its tale of God serving as a lamp upon Job's head walking through the darkness. Robyn Brothers suggests that ultraviolet light is "a metaphor for a divine force both unseen to the
