* These sizes were developed in the late 1800s and were extensions to Fresnel's design.
   The seventh and eighth-order lenses were used almost exclusively in Scotland and Canada, similar
   size lenses were known as a 'Steamer Lens' in America.
 
The radius measurements are from the focal point of the lens to the inner lens surface.
