Abstract
The antireflection of thin film was designed based on fundamental theories of optical interference coating to improve the infrared transmission of diamond. Some related parameters of the antireflective films were obtained. The antireflection effect was analyzed by the exhaustion method in inhomogeneous design for all thin films designed. The results showed that the transmission of diamond substrate coated with Y2O3 films on one or both sides were evidently increased. Y2O3 films can be used to fabricate excellent antireflective coatings for diamond as infrared optical materials.
