Development of Weak-Luminescence Spectrometer

Applications to Chemiluminescence Measurements

Abstract

Some organic materials such as plastic, rubber and foods emit ultra weak luminescence (so called chemiluminescence) during their degradation proceeding very slowly. We have developed a Weak-Luminescence Spectrometer to obtain precise spectrum data for the chemiluminescence. This apparatus was constructed on the principle of multi channel Furier-transform spectrometer combining CCD image sensor and Savart plate interferometer. Some typical chemiluminescence spectrum data for the cooking oil and some medicines were observed with the Weak-luminescence Spectrometer.
