  If the illumination of your BestScope Microscope is on but the field of view remains dark, it could be due to several reasons. First, check the contact pin and lamp holder pin to ensure they are working well. Second, the lamp bulb may be spoiled, in which case you should replace it with a new one. Third, the brightness adjustment knob might be set too dark, so adjust it to a proper position. Finally, ensure you are using the specified 6V20W halogen lamp.

  If the edge of the field of view has a shadow or the brightness is asymmetrical when using your BestScope Microscope, there are several possible causes. First, ensure that the nosepiece is in the correct, located position. Second, the surface of the lamp may have become black, necessitating a lamp bulb replacement. Third, the filament shadow may not be cleaned up; adjust the condenser knob to change the focus position and clean up the filament shadow. Finally, the lens surface might be moldy or contaminated, requiring you to clean the lens.

Why is the image defocus and low-resolution on my BestScope BS-6000A Microscope?
- K
  Kim WashingtonAug 26, 2025
  If the image appears defocus or has low resolution on your BestScope Microscope, it could be due to several factors. The objective might be damaged, requiring you to mend and correct it by sending it to the factory for overhauling. The lens of the objective and eyepiece may be moldy or have contaminants, so cleaning is necessary. The opening of the aperture diaphragm and field diaphragm might not be proper, causing too much astigmatism, so adjust their openings. The fine focus system could be broken, requiring examination and repair by sending it to the factory for overhauling. Lastly, the objective might not be in the center of the light path, so turn the nosepiece to the located position.

Why is the image focus surface inclined in my BestScope BS-6000A Microscope?
- J
  Jessica SanchezAug 30, 2025
  If the image focus surface appears inclined, with one side clear and the other faint, on your BestScope Microscope, it could be due to a few reasons. The illumination light might be seriously inclined; adjust the filament position to make the light distribution symmetrical and bright across the field of view. The specimen might not be correctly placed; ensure it is positioned properly. The nosepiece might not be in the located position; turn the nosepiece to the required position.

Why are my eyes uncomfortable when using BestScope BS-6000A and the fields of view don't coincide?
- A
  Angela HuberSep 2, 2025
  If you experience eye discomfort or the left and right fields of view do not coincide while using your BestScope Microscope, it could be due to a few reasons. The interpupillary distance might not be correct; adjust it accordingly. The diopter might not be right; adjust it according to your sight. You might not be adapted to binocular observation; when looking into the objective, do not stare at the specimen but at the whole field of view, or move your eyes away to see other things, then back into the objective.
