CHAPTER 5
TROUBLESHOOTING
Resolving Problems with the Camera
The Green LED is not lit.
■
Check all the cable connections.
■
If your camera is still not lit, then your camera may not be receiving the required power. If you have
an external power supply that outputs the power requirements needed to operate the Rolera Bolt,
connect the camera to that external power supply.
Image occasionally goes bright on one side or stays dark on one side
Turn off the overhead lights in the room. Fluorescent lights may interact with the camera to create fluctuating
image brightness.
Hazy image or poor contrast
■
If you are using the camera on a microscope, check the magnification of the microscope coupler.
Consult your microscope manufacturer to find the type of coupler that works optimally with the
Rolera Bolt camera’s sensor.
■
Point the camera at something in the far distance. Loosen the locking washer on the outside of the
C-mount ring. Adjust the C-mount ring until the image is in focus. Then tighten the locking washer
so that the C-mount ring does not move.
■
This effect may also be caused by excessive infrared (IR) illumination. Verify that your camera or
optical system is blocking the IR. Contact QImaging to order an IR filter.
Images that do not appear “sharp”
If the image does not seem “sharp,” check the format of the lens or the coupler being used on the
microscope. An incorrect coupler on the microscope will not provide the correct field of view, and will reduce
the light available to the sensor. If you experience an “unsharp” image, contact your microscope dealer to
assist you in finding the most appropriate coupler.
