Required Equipment for UV-Vis Measurements

A modular setup can be assembled in a laboratory for cost reduction purposes or for additional flexibility in being able to use the same equipment for other types of experiments, such as photocurrent measurements. At a minimum, the required equipment includes  

The choice of lamp is often dictated by the wavelength range desired for a given experiment. For work that primarily requires a large amount of UV radiation in the range of 160-400 nm, deuterium lamps are preferable. For larger ranges of 200-2500 nm, xenon and mercury lamps are suitable. Many off-the-shelf instruments contain multiple lamps to adequately cover the full spectrum of interest.
