You can’t get this range of wavelengths from a single lamp, and so a combination of two is used, a deuterium lamp for the UV part of the spectrum, and a tungsten/halogen lamp for the visible part. The two most important factors influencing the intensity and the spatial distribution of the scattered light are the wavelength of the light and the size of the particles.
