energy utilization efficiency and the imaging quality in complicated optical systems. In this work，the Fresnel

formulas of the interface between the isotropic medium and the anisotropic medium are deduced from Maxwell's equations

and boundary conditions，and the conditions of wide-angle total transmission on the optical interface are

then obtained. On this basis，a new device with the ultra-transparency is proposed at a wide angle range of [-85°，

85°]. The results should provide a new theoretical approach for designing the novel optical devices with highly efficiency
