ULTRA-LOW REFLECTANCE BROADBAND OMNI-DIRECTIONAL ANTI-REFLECTION COATING

摘要

An anti-reflection coating has an average total reflectance of less than 10 %, for example less than 5.9 % such as from 4.9 % to 5.9 %, over a spectrum of wavelengths of 400- 1100 nm and a range of angles of incidence of 0-90 degrees with respect to a surface normal of the anti-reflection coating. An anti-reflection coating has a total reflectance of less than 10 %, for example less than 6 % such as less than 4 %, over an entire spectrum of wavelengths of 400-1600 nm and an entire range of angles of incidence of 0-70 degrees with respect to a surface normal of the anti-reflection coating.
