Key Points

The aim is to understand how random thickness errors affect the properties of optical coatings using a simplified simulation.
Develop a simplified simulator to model errors in coating layer thicknesses.
Analyze the mean-root-square value of error vectors in the coating layers.
Investigate the correlation between errors and coating properties.
Errors in coating thickness significantly affect optical properties.
A clear correlation exists between the degree of random errors and the mean-root-square value of coating properties.

Abstract

Properties of optical coatings are studied on the basis of a simplified simulator of errors in the coating layer thicknesses in the course of their depositing. This approach is justified. Analytical estimates of the mean-root-square value of the norm of the error vector and the degree of error correlation in the coating layer thicknesses are derived. The dependence of the mean-root-square value of the norm of the error vector and coating properties on the level of random errors in layers is studied.
