A flat lens system includes a wedge-shaped refractive material having a first surface and a second surface opposite to the first surface for refracting incident light beams from an object having a width of Y, from the first surface towards the second surface; a reflective material positioned at the second surface of the wedge-shaped refractive material for reflecting the refracted light beams at a first angle toward the first surface, wherein the reflected light beams are refracted from the first surface at a second angle to form an image of the object having a width of X and including chromatic aberrations; and an apparatus for processing the image of the object to reduce said chromatic aberrations.
