Understand Insertion … WebOptical coatings are thin layers of oxides, metals, or rare earth metals that change a component’s optical properties. Depending on the type, number, and thickness of treatment layers, optical coatings might alter light transmission, reflection, or polarization.

The attenuation coefficient describes the extent to which the radiant flux of a beam is reduced as it passes through a specific material. It is used in the context of: • X-rays or gamma rays, where it is denoted μ and measured in cm ; • neutrons and nuclear reactors, where it is called macroscopic cross section (although actually it is not a section dimensionally speaking), denoted Σ and measured in m ; WebThe attenuation coefficient is dependent upon the type of material and the energy of the radiation. Generally, for electromagnetic radiation, the higher the energy of the incident photons and the less dense the material in question, the lower the corresponding attenuation coefficient will be.
