A review is given of the main application fields of optical thin films and various mathematical methods of their design are briefly characterised, distinguishing between analysis, synthesis, recognition and the graphical methods. Some typical design procedures, such as the use of the Argand diagram, the equivalent layer or of buffering, are demonstrated. Finally, the present and future use of computers is assessed.
