Maximum Field

The maximum field is the minimum radial coordinate that would enclose all the defined field points if the x and y values of each field point were plotted on an Cartesian XY plot. The maximum field is measured in degrees if the field type is angles, or in lens units for object height, paraxial image height, or real image height. The field type is described in the "Field angles and heights" definition. To set the field type and values, see Fields.
