What to do if the light is too dim on my Swift SW350B Microscope?
- R
  Rachel GreenAug 16, 2025
  If the light on your Swift Microscope is too dim, several factors could be responsible. First, check the iris aperture and open it wider if it's closed too far. Next, increase the intensity using the control wheel. Also, a dirty condenser lens can reduce light, so wipe it off with a soft cloth. Finally, ensure you're using the supplied power adapter, as low voltage can also cause dimness.

Why won't my Swift SW350B image focus with a higher-powered objective?

  If the image won't come into focus when using a higher-powered objective on your Swift Microscope, the slide might be upside down. Flip the slide over so the cover slip is facing up.

  If the lamp flickers on your Swift Microscope, it could be because the bulb is not inserted into the socket correctly. Check to make sure the bulb is fully screwed into the socket. Also, ensure the power adapter is fully plugged in, both into the wall socket and into the microscope.

Why is the image quality poor on my Swift SW350B Microscope?
- C
  claudiahallAug 26, 2025
  Poor image quality on your Swift Microscope can stem from several factors. Ensure a glass cover slip is placed over the specimen. The slide's thickness can impact image quality, so use a lab-quality slide. Also, check that the slide is not upside down on the stage, and if you're using oil, clean the objective lens with a soft cloth and glass cleaner. Finally, adjust the iris aperture, as an aperture that is too narrow or wide can affect image quality.

Why is the visual field uneven on my Swift SW350B?
- M
  mosleyemilyAug 28, 2025
  An uneven visual field or a dark image at the edges on your Swift Microscope can occur for several reasons. Make sure the nosepiece is locked in place to center the objective lens by turning it until you hear a click. Ensure the slide is centered over the bulb using the X-Y translational control knobs so that the specimen is fully illuminated. A dirty objective or eyepiece lens can also cause this issue, so clean them with compressed air or a soft brush. Lastly, check the iris aperture and open it wider if it's closed too far.

Why does my Swift SW350B image move while adjusting focus?
- S

  If the image moves while you're adjusting the focus on your Swift Microscope, it's likely that the slide is shifting on the stage. Reposition the slide more securely in the slide holder to prevent movement.

  A blurry or dirty visual field on your Swift Microscope can be due to a few reasons. Start by cleaning the objective or eyepiece lens with compressed air or a soft brush. If the slide is dirty, clean it with glass cleaner. Also, make sure the eyepiece or objective lens is fully screwed into place; tighten them if they are loose.

What to do if the objective lens collides with the slide on my Swift SW350B Microscope?
- B
  brendabowersSep 6, 2025
  If the objective lens collides with the slide when switching to a higher power objective on your Swift Microscope, it could be due to a few reasons. Ensure you are using a lab-quality slide or flip the slide over so the cover slip is facing up if it's upside down or too thick. Also, lower the stage with the coarse focus knob if it is set too close to the objectives. If the issue persists, adjust the safety rack stop to stop the stage farther from the objectives.

Why is the slide not moving on my Swift Microscope?
- B
  Brittney MichaelSep 9, 2025
  If the slide is not moving when using the X-Y translational control knob on your Swift Microscope, it's likely that the slide has come unclipped from the holder. Reposition the slide in the holder and secure it with the clip.

Why doesn't the lamp turn on in my Swift SW350B Microscope?
- N
  nsmithSep 12, 2025
  If the lamp does not turn on in your Swift Microscope, first check that the adapter is fully connected or that batteries are installed, as the issue could be a lack of power source. If power is not the issue, the bulb may have burned out and needs to be replaced.
