Abstract:

Discussed is a computer program that mathematically simulates production manufacturing tolerances for multilayer optical coatings. This technique operates on an ideal theoretical multilayer design by assigning random Gaussian-like film thickness errors for each layer within the film stack. N iterations of this process are performed to obtain a realistic effect of the film thickness variations on the spectral reflection and transmission characteristics of the coating. Thus, this program enables the identification of those optical coating designs that have sensitive thickness requirements and also allows for the generation of practical thickness tolerances for the many optical coatings used in fire control instrumentation.
