Similarly, for the secondary

for its contribution as a spherical mirror. For the basic afocal beam compressor, corrected for aberration, (Sj)2 is compensated by (Sj)2 by making it parabolic. In (3.20) we have for an aspheric form defined by bs2

giving, with bs2 = —1, the required compensation of (Sj)2 for the normal Mersenne beam compressor with the parabolic form. For the Paul-Baker system we require for the correction of ^Sj = 0, the condition from (3.327), (3.328) and (3.329) with a parabolic primary form

(Sj)2 + (Sj)2 + (Sj)a = o , since the tertiary is defined as spherical. This gives
