Scientific observations conclude that modern buildings can cause a high number of bird deaths due to birds’ collision with glass windows and glass walls. There are many efforts to put bird-deterrent patterns on glass in order to avoid bird collision. To make the patterns environment-friendly and meanwhile invisible for human eye, we developed a special “first surface PVD coating”. This paper describes a design for bird-deterrent stack from sputter-coating processes, our method to improve the contrast ratio between coated and uncoated area, followed by some discussions on the tunnel-test results.
