Given the increasing importance of lenses, this study has focused on designing and introducing gas lenses by putting forward the question “Is it possible to compress gas using pressure at the ambient temperature so that it forms a gas-like lens with a defined focal length?” Poly methyl Methacrylate (PMMA) and carbon dioxide were used to create the lenses. In this study, the model was simulated using ANSYS (Ver.11). This work has been done for the first time in the world. Due to the specifications of the polymer and the gas used, the focal length of the lenses was calculated at various pressures of 0.01 bar to 0.1 bar.
