CARE, FUSE REPLACEMENT AND SERVICEZEISS Troubleshooting Axiolab 5122 430037-7444-001 05/2019Problem Cause SolutionAsymmetric image sharpness,e.g. one side is sharp, one isside blurred.Condenser is not correctly adjusted. Adjust the condenser correctly;see p. 81 ff.Nosepiece is not engaged in its lockingposition.Engage the nosepiece in its lockingposition (click-stop).The specimen has not been fixed on themechanical stage.Insert and fix correctly in the specimenholder.Distinct focus differences whenchanging the objective.Focusable eyepieces are not adjustedcorrectly or a Pol eyepiece was used in abinocular tube without upright image.Adjust the focusable eyepiecesaccording to the vision defect,see p. 79.Objective is not screwed in all the way. Screw the objective in to the stop.Tube lens is not mounted, or mountedunnecessarily.Mount the tube lens or remove it, asappropriate.Left and the right field of viewcannot be brought together inone image.Eyepiece distance (inter-pupillarydistance) is not adjusted correctly.Adjust the inter-pupillary distancecorrectly;see p. 79.Focusable eyepieces are not adjustedcorrectly.Adjust the focusable eyepiecesaccording to the vision defect,see p. 79.Eye fatigue when using themicroscope.Eyepiece distance (inter-pupillarydistance) is not adjusted correctly.Adjust the inter-pupillary distancecorrectly;see p. 79.Focusable eyepieces are not adjustedcorrectly.Adjust the focusable eyepiecesaccording to the vision defect,see p. 79.Image brightness is unacceptable. Adjust the lamp voltage or insert aconversion filter.Binocular tube is optically/mechanicallymisaligned.Call in service personnel forcheck/repair.Dirt or dust in the field of view. The condenser has not been correctlyfocused and front lens 0.9 not swiveledin/out correctly.Focus the condenser and swivel frontlens correctly in or out;see p. 81 ff.Opening of the aperture diaphragm is toosmall.Set the aperture diaphragm as per2/3 rule or the specimen features;see p. 81 ff.Dirt or dust on optical surfaces ofobjectives, eyepieces, condensers, filtersor specimens.Clean the optical surfaces of thesoiled components,see p. 119.
