摘要：
A lens switching system is provided for use in X-ray examination devices. The lens system includes at least a full viewing lens for viewing the entire object and a magnification lens which can be switched into the optical axis and controlled to different positions for magnifying the object. The optical axis for the magnification lens can be moved by means of a control handle controlling the lens system so that magnified portions of the object can be observed through the magnification lens.
