Calculation and considerations on the response function of photographic lens (where aberration beyonds 2λ) are given. Response function for some types of aberration and different focus positions are calculated numerically from geometro-optical response.
Results are represented by contour lines in focus position versus spatial frequency at the following three cases.
1. Primary spherical aberration alone.
2. Primary and secondary aberrations, and
3. Primary, secondary and tertiary aberrations.
Response function are evaluated as their integrant with weighting function (receptor's response function), consideration on position of the best focus and the best correction of spherical aberration are described.
