Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Image is blurry or out of focus. | Incorrect distance to object; phone camera not zoomed correctly; lens not aligned. | Adjust the distance between the microscope and the object. Use your phone's digital zoom. Ensure the microscope lens is perfectly aligned with your phone's main camera. |
| LED light does not turn on. | Battery is low or depleted; switch button not pressed correctly. | Charge the microscope fully. Press and hold the light switch button for 3 seconds to power on. |
| Excessive glare or reflections in the image. | Shiny object surface; CPL lens not optimized. | The integrated CPL lens should reduce this. Ensure the object is well-lit but avoid direct harsh light sources. |
| Microscope does not fit on phone. | Phone thickness or camera position outside of adjustable range. | Verify your phone's dimensions against the microscope's adjustable clip range (4mm-20mm thickness, 26mm-39.5mm camera distance from top edge). |
