Abstract. A method of optimal choice of materials for passive optical thermostabilizing is presented. A graphic method is proposed for design of two-component achromatic thermostabilized lens with one of the components being synthesized from two sub-components to create the missing dispersion and the temperature characteristics of the materials to correct chromatic aberration of the lens position and thermos-responsive image defocusing.
Keywords: athermalization, achromatization, graphic method
