The traditional approach is no longer sufficient

Abstract

Optical coatings play an enormous role both in our daily life and in advanced research. Virtually any optical element – from a simple lens to the ones used in the sophisticated laser systems, space instruments or data transmission cabinets – have optical coatings. New designs of the coatings and new applications require an upgraded and often designed‐from‐scratch technology to meet the continuously growing thin film optical metrology specifications.
