Does anyone know what the absorption coefficient of aluminium? Or at least where I can find it. Thanks in advance!

The absorption coefficient of aluminium refers to the measure of how much light or radiation is absorbed by a material as it passes through it. It is a unitless quantity and is typically represented by the symbol α.
The absorption coefficient of aluminium is determined by conducting experiments where a known amount of light or radiation is passed through a sample of aluminium and the amount of light that is absorbed is measured. This data is then used to calculate the absorption coefficient using a specific equation.
The absorption coefficient of aluminium can be affected by various factors, such as the thickness and purity of the aluminium sample, the wavelength of the light or radiation being used, and the temperature and pressure of the environment in which the sample is being tested.
The absorption coefficient of aluminium can vary significantly from other materials, as it is highly dependent on its composition, structure, and properties. Additionally, different materials may have different absorption coefficients at different wavelengths of light or radiation.
The absorption coefficient of aluminium is an important parameter in various fields such as optics, material science, and engineering. It is used to understand how light or radiation interacts with aluminium and can be used to design and optimize various applications, such as solar panels, optical filters, and reflective coatings.
