Proposed Classification

U. S. CL 355/55

mt. Cl, GO3ID 27/52

An optical system for projecting an image of an object,

operating between fixed object and image planes

                                       0 Both
the object conjugate and the image conjugate are variable
to vary the magnification in the system This is

accomplished without moving the optical axis by means of
a first roof mirror on the object side of the lens and a
second roof mirror on the image side of the lens, These
mirrors each fold the optical axis by 90° and are movable
along a locus at 45° to the optical axis to change the
object and image distances.
