Lamp wavelength

WebbThe white continuous light generated by the xenon arc is spectrally similar to daylight, but the lamp has a rather low efficacy in terms of lumens of visible light output per watt of input power. Today, almost all movie … Webb14 mars 2024 · Deuterium lamps produce intense ultraviolet (UV) radiation at wavelengths between 190 and 400 nm via plasma discharge in an atmosphere of deuterium. Light with a wavelength below 190 nm is not readily transmitted, as it is absorbed by the lamp’s quartz envelope. These lamps, as is the case for any light bulb, have a finite lifespan.
