| Abstract | ||
| In this paper have been overcome the difficulties regarding designing multi- layers anti-reflection coatings (ARCs ) and achievement optimal designing for IR (3-5um) region by adopting needle technique as optimal method . Here intend to investigate solutions for many practical problems. This work appears designed (ARC) that have good performance with reduction the number of layers, which can enable one to controlling the errors effect of the thickness layers on the final product. Results shows that choosing optimal Merit Function Besides, most of results referred to the suggested designs which are very effective, in building the anti- reflection coating filters and gives big potential to reach complex optical coating match the optimization characteristics of the optical performance with less number of materials with less thickness. Results shows that the construction of multilayer antireflection coating using in this approach can be designed with most complicated performance, and it is difficult designing in other approach .Also this work appears needle method able to control of problem material coating selection | ||
