Stray light limits the maximum absorbance level achievable with a given spectrometer. Once the stray light limit is reached, sample dilution or a smaller pathlength is required to measure more concentrated samples. In this application note, we show the impact of stray light on the maximum absorbance level and describe how optimizing the choice of light source can minimize stray light and increase the maximum absorbance measured.
