ULTRAVIOLET-LIGHT SOURCES144. Ultraviolet-light sources are lamps which are designed primarily to produce light of wavelengths in the ultraviolet part of the spectrum (see Fig. 10.1). It should be understood that not all ultraviolet light is the same. There are at present four recognized bands of ultraviolet light. The band in which the light from any source falls depends upon the wavelength of the light emitted. Each of the recognized bands differs widely from the others in its characteristics, usefulness, and field of application. The four bands are as follows: the near-ultraviolet or fluorescent region, the erythemic region, the abiotic or bactericidal region, and the Schumann region. They are liste…
