and AAS from Table 6.9, and letting m ^^ oo. Note that in the afocal
limit there is no difference between the classical and aplanatic types.
We now determine some of the characteristics of pupils and chief ray
directions. From Table 6.3 we see that mk is the normalized distance from the
secondary to the focal point, while from Eq. (2.6.1) we find that the normalized
distance from the exit pupil to the focal point is S. For an afocal telescope the
ratio S/mk = 1, or S/m = k. Substituting this result into Eq.
