Abstract
A method to design a dialyte based on the caustic surfaces is presented, with
correction at the third-order spherical aberration. We predefined,
a priori, the value for the back focal length of the
separated doublet for two different wavelengths to calculate their
radii of curvature, which depend on all the parameters involved in the
refraction process. Additionally, we approached the caustic surface by
applying a Taylor series, which provided the analytical spherical
aberration coefficient at the third order. Two alternatives to design
achromatic separated doublets are provided. Finally, we extended the
method to design achromatic cemented triplets.
