WebAberration can be defined as a departure of the performance of an optical system from the predictions of paraxial optics. [2] In an imaging system, it occurs when light from one point of an object does not converge into (or does not diverge from) a single point after transmission through the system.

In addition, unless we … WebThe aberrations and properties corresponding to these Zernike terms are shown in Table IV. Writing the wavefront expansion in terms of field-independent wavefront aberration coefficients, we obtain (58) Because there is no field dependence in these terms, they are not true Seidel aberrations.
