Why is the field of view not bright enough on my AmScope 120 Microscope?
- A
  Amanda HernandezAug 22, 2025
  If the field of view on your AmScope Microscope isn't bright enough, adjust the iris diaphragm to allow the light to be just larger than the condenser. Also, adjust the condenser height to the top of the travel range, then adjust down to focus the image. Ensure that all lenses (condenser, objective, eyepieces, and base lens) are clean; thoroughly clean them with lens cleaner or a lint-free nonabrasive cloth.

Why is the bulb/light source flickering on my AmScope 120 Microscope?
- M
  Matthew SmithAug 26, 2025
  If your AmScope Microscope's bulb or light source flickers, it might seem like the bulb is burning out. However, the unit’s LED bulb should not burn out, so the bulb is likely not the issue. Please contact customer service for warranty repair information.

  Robert CarrAug 28, 2025
  If your AmScope Microscope does not light up, first, ensure that it is properly plugged into the wall socket. If it is plugged in, but still doesn't light up, the bulb may have burned out. However, the unit’s LED bulb should not burn out, so the bulb is likely not the issue. Please contact customer service for warranty repair information. Also, check the fuse; if it has burned out, replace it with the fuse on the bottom of the microscope.

  If you're having trouble moving the slide smoothly on your AmScope Microscope, first, adjust the slide to use the stage clips and secure the sample correctly. If the issue persists, tighten the mechanical stage screws to better secure the stage.

What to do if the objective touches the cover slip on my AmScope 120 Microscope?
- T
  Tricia ParsonsSep 4, 2025
  If the objective on your AmScope Microscope touches the cover slip, replace the cover slip with the appropriate 0.17mm thickness slip, as the cover slip may not be standard-sized. Also, be careful to avoid contact between the objective and the slide when the limit stop is up (unless using the 100x objective with oil). To reengage, focus the sample, then lock the limit stop into place at the stage height to set the max height at a safe but usable distance.

  If the color of the image on your AmScope Microscope is not accurate, adjust the brightness knob to a higher or lower setting for color clarity. Also, remove any color filter if natural light is desired, or insert the desired filter.

  Tara DavenportSep 7, 2025
  If you cannot see anything in the camera or the image is black when using the trinocular port on your AmScope Microscope, slide the silver metal pin out on the head of the microscope to allow light to reach the trinocular port. This opens the trinocular port shutter.
