ABSTRACT:
A vessel holds a liquid content for exposure to prescribed light energy. The vessel has a region transparent to the prescribed light energy. The liquid content of the vessel includes a solution comprising a material undergoing reduction oxidation as a result of exposure to the prescribed light energy, and a reducing agent for the photoactive material. A device measures optical absorbance of the vessel and the liquid content. The device operates in a first instance to measure a first optical absorbance value before exposing the vessel and the liquid content to the prescribed light energy. The device also operates in a second instance to measure a second optical absorbance value after exposing the vessel and the liquid content to the prescribed light energy, to obtain a difference between the first and second optical absorbance values. The difference comprises an illumination characteristic for the vessel with respect to the prescribed light energy.
