Abstract: The applications of reflected and red transmitted film have been analysed. The quarter wave-pile method was been adopted to design the quarter wavelength reflected red film. Thelen analytical method was been introduced to design the quarter wavelength red transmitted film.The film system design of two kinds of non-quarter red wavelength flim were completed by means of the genetic algorithms.Using advanced computer language MATLAB, it have been given all design results of two kinds of red film and corresponding spectrum characteristic curves.
