This paper reports a new super-resolution, "saturated" imaging method using a flat slab of photonic crystal with negative refraction. The photonic crystal has hexagonal lattice with holes in dielectric material with an index of 3.6. When the operating normalized frequency is around 0.30, the effective refractive index is -1. Such a flat slab lens can tolerate disk deformation of approximately one-wavelength or more while maintaining the same super-resolution as the near-field imaging of the photonic crystal slab. The object distance can be as large as twice the slab thickness, and the resolution is about 0.43λ.
