A novel planar zoom module (PZM) is presented in this article. The PZM is realized by integrating optical elements on its surfaces with the folding optical axis and performing the zoom function by transversal rotation or motion. Its application as a ltimagnification beam expander is designed, analyzed, and demonstrated.
