Peer Review History: Diffuse Reflectance of Powders

The propagation of light through powders differs significantly from the propagation of light in a homogeneous material, since the light scatters off points in its path. Colors of powders are related to the fineness of the powder, when the powder is illuminated with white light. As Fourier transform infrared has become more common, the diffuse reflection method has become widely used. Diffuse reflectance is an excellent sampling tool for powdered materials.
