In this study, the focusing function of infrared microscope has been fully authenticated. The testing method adopted in the study is to directly focus infrared light spot on the sample’s surface by infrared microscope in order to collect its spectra. The research purpose is to distinguish ink marks of different brand ballpoints with the same color by making a qualitative analysis to the number, position, intensity and shape of the samples’ IR absorption peaks. Studies show that the testing method can effectively distinguish ink marks of different brand ballpoints with the same color and keep the intactness of physical evidence with the characteristic of nondestructive testing.
