In an image formation system, at least two copying machines are connected to each other. The substrate has an upper surface and a termination including a trench extending into the substrate from the upper surface within the termination region. The electrochromatic layer may include an electrochromatic material that is structured to display a color, to appear black, or to become transparent according to a voltage applied thereto. In other embodiments, a method of improving the resolution of an optical device may include translating a lens along an optical axis to maximize resolution at a first location, and determining a resolution in a second location in the imaging plane.
