Abstract
Optical systems (1-19) for endoscopes and the like are characterized by an integrated design in which the locations of the components and the aberratio n corrections are no longer tied to the optical functions of the objective (1- 6) and the relays (7-19), and in which the relays may depart from symmetry. The power requirements can thus be shifted from one group to another, thereby reducing the overall power requirement. Moreover, the aberration correction can be shared between the optical groups of the integrated system.
