Abstract

The paper is focused on the behavioral simulation of the lenses, defined by geometric characteristics (radius, thickness and diameter) and material characteristics, for a certain incident wavelength. The simulation provides a representative layout of the raytracing for refraction and for the second and third reflection on lens surfaces. At the same time, the user can display the rays distribution on a normal plane related to optical axis direction. The authors designed the simulation program and a graphic user interface as a tool to evaluate the parasite images caused by multiple reflections in the specter available for chosen material. Thus, the image disparity for a certain parameter will influence the transmittance through lenses for some radiation or specter. The simulation program is designed to be used in optics, optometry, to analyze the behavior of refractive components and can predict the useful diameter of lenses, diaphragms or aperture stop. The program is also useful, for example, for anyone interested to see how lenses work if the internal reflection of the light on the lens surfaces is considered. The idea of the program comes from the fact that with other ray tracing software and their toolboxes, the multiple reflections are not obvious. The developed simulation program and interface can highlight the ray distribution in an image plane as being suggestive for the ghost images presence and of lens aberrations. Also, there can be easily predicted some geometrical placements in the optical layout, the dimensions of the main apertures and the position of the second order images due to multiple reflection and refraction.
