Abstract
A device for shifting the imaging axis of a microscope across the endfaces of a multi-fiber connector for inspecting the endfaces comprises: a supporting body attached to the optical tube of a microscope and having an extended portion; a swinging lever mounted at one end to the extended portion of the supporting body and rotatable on an axis perpendicular to the imaging axis of the microscope; a connection piece connecting between the swinging lever and a fitting tip; a bevel wheel fastened to the supporting body; and a torsion spring for pushing the swinging lever against a slanted surface of the bevel wheel. The bevel wheel is adapted to swing the swinging lever relative to the supporting body so that the imaging axis of the microscope is moved relative to the fitting tip to selectively align the imaging axis across the endfaces for inspection.
