We present a design thin film multi-cavity Fabry-Perot filter. These filters are most widely used filtration technologies that made technical advancement of the modern optical communication system possible. This paper is concerned with a theoretical study to design and analyze this type of filter. A brief introduction to the thin film multi-cavity filter technology will be presented. The recent progress in thin film multi-cavity designing technology will be reviewed. These designs consist of two materials as high / low index. The wavelength range from 300nm to 500 nm. The filter is to be coated on Fused Silica having index 1.55 and operates at normal incidence.
