Hamamatsu L2482 Super-Quiet Mercury Xenon Lamp has an output of 185 to 2000 nanometers with Fused Silica window material. Mercury-xenon lamps produce high radiant energy especially in the ultraviolet region due to an optimal mixture of mercury and xenon gas. These lamps possess features of both xenon gas and mercury discharge lamps. The spectral distribution includes a continuous spectrum ranging from ultraviolet to infrared of the xenon gas and strong mercury line spectra in the ultraviolet to visible region. Compared to xenon lamps, the radiant spectrum in the ultraviolet region of mercury-xenon lamps is sharper in width and its peak is higher in intensity. These features make mercury-xenon lamps ideal as ultraviolet light sources.
