Lamps for UV VIS spectroscopy

Lamps for UV VIS spectroscopy

UV/VIS spectroscopy is a method to measure the absorption of visible light (390 nm to 800 nm) and UV light (190 nm to 390 nm). The substances are measured in solution contained in a quartz cuvette.
Using a spectrometer, light with a wavelength range of 190 nm to 800 nm is radiated through the cuvette and absorption spectrums are recorded. The broadband light sources used for this are deuterium lamps (UV) and tungsten halogen lamps (VIS, visible).
Mercury lamps that emit just a line spectrum are also used.
