Durable Silver - Based Antireflection Coatings and Enhanced Mirrors

Various types of thin film designs which incorporate silver metal are well known. The chemical and mechanical durability of these films is usually poor. This fact limits the practical application of the films. A new process has been developed which allows the use of silver metal in various types of thin film designs such as wide-band anti-reflecting and wide-band high reflecting films. This paper describes the patented process and designs used to deposit these film stacks.
