WebReflectance is the ratio of energy reflected to the total energy incident on a body, expressed in percentage. An object appears green because it reflects only wavelengths corresponding to green color in the visible spectrum. ... The reflectivity rises rapidly near 0.75μm and remains high in the NIR region in the range 0.75 to 1.35μm. The peak ... WebReflectance and roughness are both connected by local areal surface gradients according to the scheme: Reflectance -> Surface gradients -> Surface roughness (texture) An integration stage is ...

WebFactors affecting Reflectivity: Thickness, Pore Size, and Other Correlations The porosity of PTFE, relative to solid PTFE, can have a significant effect on a materials’ reflectance properties. Porous PTFE sheet samples at 2 mm thickness showed a reflectivity over 97%, and we expect the reflectance of thicker samples to be even higher. http://www.differencebetween.net/science/difference-between-albedo-and-reflectance/
