Analysis of Coatings on Intractable by Panels by Diffuse and Specular Reflectance Probes 

 

Spectra of coated metal samples collected with diffuse and specular reflectance FlexIR probes are 
illustrated on the following page. Figure 6 shows a spectrum of a coating on a smooth reflective surface 
(coating on the outside of a soda can), conducive to specular reflectance measurements. The second 
sample featured a painted surface with diffuse reflectance characteristics (Figure 7).
