Abstract
An optical system for viewing an object has a plurality of lenses and a main optical axis coincident with the centers of the lenses. The optical system further comprises a low magnification optical subsystem that is operative to view the object at a first magnification and a high magnification optical subsystem that is operative to view the object at a second magnification that is higher than the first magnification. The high magnification optical subsystem has a high magnification optical axis along which light rays that are received from the main optical axis are transmitted. A movable element is locatable on the high magnification optical axis and is movable in directions transverse to the axis for receiving and transmitting light rays.
