ABSTRACT:
Interference filters having a vapor deposited layer of a silicon oxide adjacent to a vapor deposited layer of silver have adhesion between these layers improved by a very thin intermediate coating of chromium, nickel or an alloy containing about 90% chromium and nickel. Plastic articles having infrared reflecting interference filters with improved adhesion between layers, such as lenses and welding faceplates, are also disclosed.
