Аннотация:Color properties of a multielement optical lens are usually described by a color formula which depends on lens design, optical properties of materials, and transmission coefficients of applied AR coatings. If color properties are of importance in lens design we receive a multicriterion optimization problem. To solve the problem one can use a special choice of coatings from the available coatings set and change continuously some AR coatings parameters also. The user-friendly software was expanded, which allows simultaneous optimization of color and transmission properties of modern multielement optical lenses.
