Application of optical design software in analysis of "unknown" optical systems

Optical design software is not very usable in designing new optical systems only, but also in analysis of "unknown" systems. When measurements of radii of curvature, focal lengths and axial thicknesses of elements are done, we use SIGMA 2100 Optical design software (Kidger Optics). We determine which optical glass fits the nearest measured focal length of each element. We also get aberration curves of elements and the whole system. In such a way we analyse elements of an eyepiece which is the part of a compound panoramic sight. Since we now have all specifications of this eyepiece, it is possible to optimize glasses and radii to the more convenient ones, without a risk to change the performance of the whole optical system. This method gives us the possibility of reparation and adaptation of "unknown" optical systems with a high yield.
