Spectrophotometer with high sensitivity and wide dynamic range have been requwired. In previous presentation, we reported that the development of the spectrophotometer enabling the measurement for the filter with over OD10. In this presentation, we will report that the evaluation of the spectrophotometer using aqueous solutions with several absorbance.
