Abstract
We present experimental results for passing of optical vortex (OV) through cylindrical lens. Process OV transformation by cylindrical lens doesn't considered in detail before. OV change the sign of topological charge after focus. At this situation emerged the question: 'What does happen with orbital angular momentum?' because the conservation laws of topological charge and orbital angular momentum must be safe. Answer on this question can give more information about propagation of OV and about of transformation orbital angular momentum within combined beams.
