Method and apparatus for processing spectrum in spectral measurement

摘要

The apparatus for processing a spectrum in spectral measurement includes: a measurement section 10 for measuring an energy spectrum of light for measurement from an object to be measured; an addition section 11 for adding a predetermined value to the energy spectrum of the light for measurement; and a conversion section 12 for obtaining an absorbance spectrum with reduced noise by effecting absorbance conversion of the energy spectrum of the light for measurement with the addition of the predetermined value.
