- EewatsonAug 13, 2025
If dust is visible in the field of view, check if there is dust on the specimen and remove it. Also, check the eyepiece for dust and remove it.

How to remove dust visible in the field of view of Olympus SZX12 Microscope?
If dust is visible in the field of view, check if there is dust on the specimen and remove it. Also, check the eyepiece for dust and remove it.
Why is the field of view cut off or unevenly illuminated on my Olympus Microscope?
The field of view may be cut off or unevenly illuminated because the aperture iris diaphragm is stopped down excessively. To fix this, open the aperture. Also, check if the observation tube and intermediate attachment are not correctly mounted; if so, mount them correctly. For SZX-TR30 models, ensure the light path selector knob is correctly set to the desired position.
What to do if the image is not sharp on Olympus Microscope?
If the image appears unsharp or lacks sufficient contrast, make sure the objective is correctly mounted until it stops. Also, check the objective front lens for dust and clean the lens surface if necessary.
How to fix incomplete binocular vision on Olympus SZX12 Microscope?
Incomplete binocular vision can occur if the interpupillary distance is not correctly adjusted; adjust it correctly. It may also happen if the diopter adjustment is incomplete; complete the diopter adjustment. Finally, ensure that you are using a pair of matched eyepieces.
What to do if specimen image blurs when zoom magnification is changed on Olympus SZX12?
If the specimen image blurs when the zoom magnification is changed, the diopter ring may not be correctly adjusted. Adjust it correctly. Also, ensure that the specimen is in complete focus; focus the specimen correctly at a high magnification.
Why is there excessive image contrast on my Olympus SZX12?
Excessive image contrast can occur if the aperture is stopped down excessively, especially when using the built-in aperture iris diaphragm and SZX-AS. To resolve this, open the aperture to the proper diameter.
What to do if coarse focus adjustment knobs rotate with too much resistance on Olympus SZX12?
If the coarse focus adjustment knobs rotate with too much resistance, the tension adjustment ring may be too tight. Loosen it properly.
Why does the zoom microscope body drop or specimen go out of focus during observation with my Olympus Microscope?
If the zoom microscope body drops or the specimen goes out of focus during observation, the tension adjustment ring may be too loose. Tighten it properly.
