Abstract: According to the basic idea of genetic algorithm and focusing on the field of optical coating, this paper introduced a way to implement genetic algorithm for optical coating designing optimization. This approach included detailed operational steps in “building population” “building fitness function” “selection” “crossover” “mutation”and“elitist strategy”. Based on this method, an optimal design example of implementing 4 passbands in 400-900 nm was given. The result shows that this method can achieve better optimization effect in coating system design. At the end of the paper, we pointed out that this method only realized simple genetic algorithm, and it had a large space for improvement in operation efficiency and optimization ability.

Key words: optical coating, genetic algorithm, optimization, design of coating system
