The state of the art conformal optics is described. Conformal optics refers to the design, fabrication and use of optical windows and domes that are neither flat nor a section of a sphere. The challenges and solutions to overcome the challenges associated with developing the tools and techniques that enable the use of conformal optics is described. A demonstration of the utility of conformal optics is presented.
