Investigation of degeneration mechanism and improvement method of infrared (Ge/SiO) stack filters
The degeneration mechanism of characteristics of infrared (Ge/SiO) stack filters is discussed based on experimental results. We propose a method to prevent such degeneration of characteristics. By using the method, high-quality filters have been obtained which can withstand immersion tests in water and solutions of salt or acid.
