As DOE have special dispersion, small volume, light weight andcan be relicated, it plays more and more important role in national defence, production and science research. Its application in optical imaging system can not only improve imaging quality, but also perform system's lightweight, miniaturization and increase degree of freedom in the design. The 16-step Fresnel lens had been fabricated by ion beam etching and it has been used in refractive-diffractive CCD camera. Its diffractive efficiency is measured and the factors to affect it are analyzed
