A meridional ray tracing software development for lens design

In this thesis a simple meridional ray tracing software which can be used in the optical lens design is developed. The first version of this software is called Heysem 1.0 which has both paraxial and exact ray tracing capability. Heysem has a simple Graphical user Interface (GUI) to input the lens radii, thickness, number of rays and etc required in the design. It gives some output the system layout, a summary table and some basic lens aberration calculations and plots to the user. The outcomes and plots obtained in heysem are compared with zemax OpticStudio program. It is found that the ray tracing computations and plots in both softwares are the same.
