Paper Abstract

The optical system working under the condition of a radial thermal gradient change its nominal constructional parameters, such as: radius of curvature, thickness, interlens separation and refractive index. These changes have two aspects: first one caused by pure temperature change and the second one is related to the thermal gradient distribution. In the first case well known temperature changes of constructional parameters are encountered (area of the athermalization problem) and in the second one known gradient index changes in optical material are faced. In this paper the problem of the aspherization of optical surfaces due to the radial thermal gradient is taken into account. The rapid method for evaluation of aspherical parameter CC (conic constant) applied in the optical design is presented. The obtained results are verified by the finite element method as well as the interferometric experiment.
