Description
Summary:The article deals with the method of field curvature correction in wide-angle objectives and technique of its implementation. The correctional elements were used with definite values of longitudinal magnification along the chief ray to solve the problem of correcting components synthesis. Design parameters of these elements were related mathematically with its real aberration, in particular, the aberration of astigmatism.
