Figure 7
Ray spot diagrams (I) and (II) corresponding to the images of optical system I with an image plane of = 400 mm and optical system II with an image plane of = 668 mm, respectively (axis units: mm). Panels (a) and (b) are obtained using the ray-tracing software Shadow and the aberration expressions derived in this paper, respectively. The field angles are shown on the right-hand side of each row. |
