External reflection using IR spectroscopy is effective for examining paintings, polymer-coated metals like soda can coatings, and even bulk polymers. Shiny, metallic surfaces provide a strong specular reflection spectrum that matches standard absorbance spectra very well. Less-reflective surfaces, like dark plastics, may require additional software processing.
