Emission spectra of ultraviolet lamps. All of the long wavelength (366 nm) lamps with manufacturer’s filter in place emit a single broad band that peaks at 366 nm. A polystyrene filter transmits the emitted band. In contrast, the short wavelength (254 nm) lamp emits the polychromatic spectrum characteristic of a mercury lamp. The relative intensities of the emissions vary from lamp to lamp. These emissions are transmitted through a quartz filter but the 254 nm band does not pass through polystyrene.
