Paper Abstract

To increase the strength of infrared high efficiency antireflection coatings is a problem difficult to be resolved. A mixture of BaF2 and CeF2 has been used as a low refractive index material to design and prepare infrared 8 - 11.5 (mu) high efficiency anti-reflection coating to acquire good strength of film layer. The processing conditions of the films deposition have also been introduced. The spectral transmittance measured, physical and chemical properties of the infrared anti-reflection coating are given.
