POST-FOCAL AND PRE-FOCAL TWO MIRROR SYSTEMS
Abstract
While investigating a potential of two-mirror systems with spherical surfaces for searching new solutions it looks rather reasonable to delineate fields of schematic solutions classifying possible and well-known types of systems along motion of zero ray in the system. As a result of the investigations a classification has been made in three types of systems along motion of zero ray in an objective.
Calculation of aberration factors of 3-power has shown that systems of the first type have the highest potential because astigmatism and curvature are corrected there in a better way that specifies objective resolution. A disadvantage of these systems is a high central screening.
