AUTOMATION OF ATHERMAL CEMENTED DOUBLET SYNTHESIS
Annotation
Subject of Research. The paper considers the problems of synthesis and analysis automation for the cemented doublet with the possibilities of achromatization and synchronous passive athermalization. We present an algorithm for such automation and give an example of the cemented doublet development using this algorithm. Methods. Component synthesis with regard to achromatization consists in selection of a pair of glasses and calculation of the curvature radii for a system of two infinitely thin cemented lenses with given values of three parameters determining the spherical aberration of the third order (P), the thirdorder coma (W) and chromatic aberration (C) according to Slusarev procedure. Passive athermalization is performed using the method of nomograms. In contrast to the traditional visual selection of a pair of glasses, a value is calculated for evaluation of the system thermo-optical properties and the result is displayed in the summary table. Main Results. The developed algorithm gives the possibility to extend the modular design principle most commonly used for aberrational calculationsto the calculation of thermal defocusing. An example of algorithm application is given demonstrating defocusing value less then diffraction focus depth. Practical Relevance. The developed method simplifies and speeds up the stage of materials selection for the designer or engineer during the preprocessing calculation of the cemented doublet from two lenses; evaluates the balance of aberrations in general and the calculated component behavior with temperature changes; performs comparative analysis of several similar system variants.
