SPECTROPHOTO METER COMPRISING A XENON FLASHTUBE AS A LIGHT SOURCE

摘要

The disclosure relates to a spectrophotometer using a pulsed xenon flashtube as a light source (1). The energy to be applied to the light source (1) of the spectrophotometer is set to be from 0.03 joules to 1.0 joule. Therefore, the intensity of light emitted from the light source is not so intense which allows the spectrophotometer to measure a spectral reflectance under the presence of a natural light or equivalents. Further, the charging period of time required for the spectrophotometer to provide a desired light emission intensity is short, so that the light source (1) is capable of emitting many flashes per second, whereby the number of data acquired within a predetermined measuring period is increased. Thus, accurate data can be obtained.
