Mirrors added as supplemental mirrors to vehicles offered by mirror manufacturers use the single rate of curvature mirror which always produces objects that are smaller than the object viewed resulting in confusion to the operator as to the location of the object in relation to the operator of the vehicle. This confusion is many times referred to as distortion. Our goal at M-C North America Inc. was to design a spot mirror glass that could produce the wider view while at the same time eliminating the distortion found by providing a wider view without image size being reduced. The end result was the M-C Glass Technology that produced a mirror glass that was so unique it has been granted a US Patent (No. 8,172,411).
Following photo illustrates the respective size of images produced by our technology in an 8 x 8 piece of our glass as compared to the size of images produced by the standard 8 inch convex mirror:
