Fig. 10.10. Normalized rms wavefront error oj' and Strehl ratio S for image with spherical
aberration as a function of image surface location. S is given for co' = 1, w = 0.075A at / = 1. The
normalized focus shift is /. P, paraxial focus; M, marginal focus; C, circle of least confusion.
Following a similar procedure, it turns out that a system with astigmatism has
a minimum oj and maximum /(O) at a point half way between the sagittal and
tangential line images for any value of
e.
The distance between the line images is
IF TAS, where TAS is given in Eqs. (5.5.9). After substituting B^ from Eqs. ...
