INVASTIGATION OF THREE MIRROR ANASTIGMATIC AXISMETRICOBJECTIVE WITH CORRECTED DISTORSIA
Journal Title: Международный научный журнал "Интернаука" - Year 2018, Vol 1, Issue 6
Abstract
The article analyzes the variants for the characteristics of the three-mirror anastigmatic lens.There were used formulas in which distortion was corrected in the lens. These formulas are used for calculating the design parameters of the mirrors and the positions of the focal plane and the plane of the intermediate image at given focal length of the objective and the distances between the mirrors. Obtained design parameters allow choosing the optimal variant of the objective, in which all five third-order aberrations are corrected (spherical aberration, coma, astigmatism, curvature of the field of view and distortion).
