Designing and Inspecting the Metal's Steam (PVD) on Aluminum and Investigating it's Optical Properties

Considering the reflection theory and numerous applications of the mirror, we can achieve mirrors with thin-film, metal-dielectric coatings. Hence, in this article, with respect to the above-mentioned approach and using new materials, a mirror with maximum reflection of nearly 100% and of aluminum alloy is produced. Metal mirror is a very good reflector with a wavelength of 3 to 5 micrometers. The optimum intermediate layer for inspecting metals' steam is aluminum oxide. This compound has higher stabilization compared to other intermediate layer substances. After optimizing the accumulation conditions and calculating the number and thickness of layers and the interface, the resulting collection was designed. The physical vapor method (pvd) and the thickness of layers are measured by optical method. By conducting qualitative tests and examining reflection spectrum, the durability and stability of the set have been investigated. The mirror aluminum has more than 99% reflection in infrared field.
