Abstract

Effective antireflection coating designs for infrared windows are developed for the 3-5 micron and 8-12 micron bands. Dual band performance with these designs are optimized with computer aided techniques. A simple scheme to improve their oblique incidence performance is examined. Potential use of these designs in practical coatings without the use of radioactive materials is also discussed.
