Abstract

In this paper, study has been made for development of high reflective optical coating. Multilayer dielectric system with high reflective indices (TiO2 n = 2.45), and low reflective indices (SiO2 n = 1.4) is used to achieve the high value of reflectivity in visible range. In house developed MATLAB computer program is used to design and simulate the optical coatings. The results shows that the width of high reflectance region decreases, and reflectance increases with the number of layers in the stack. To compare with the theory, preparation of high reflectance coating has also been carried out using e-beam evaporation system. Optical properties of the prepared film studied through optical reflection measurement.
