Webthe sign ofa21 indicates whether the optical element (or combination of elements) is focusing or defocusing. An optical element is defined as any region in a focusing system that operates on an orbit vector to change the orbit parameters. Thus, there is a transfer matrix associated with translation in field-free space along the z axis (Fig. 8.2).
