RESUMO
We discuss the optical recording and relaxation of low spatial frequency gratings and negative microlenses by a dyed polyacrylamide gel. An analysis of the grating diffraction efficiency and the focal distance of microlenses is shown. A study of the evolution of the surface modulation of both types of elements with an interference microscope is also included.
