The collect of capillaries into polycapillaries and x-ray lenses offers many possibilities in several scientific fields: physic, astronomy, industry, medical imaging. Before buying and using a system based on capillaries, one needs to simulate the performance of various kinds of x-ray optics. In order to predict the behavior of such optical system a simulation program has been developed to test all kinds of capillary optics available on the market. This report is exhibiting theoretical methods used to assess transmission, exit divergence and image obtained behind a polycapillary just as an x-ray lens. The simulation program can test many kinds of optics based on capillaries in the energy range 1- 80 keV. Some experimental comparisons have been achieve din order to guarantee the validity of our simulation result. By means of this simulation program, one can optimize an x-ray lens to put in an optical chain with respect to experimental conditions and restraints.
