Resolving Problems with the camera
CHAPTER 6
The White LED is not lit.
• Check all the cable connections.
• Press the switch at the back of the camera.
• If your white LED is still not lit, then your camera may not be receiving the required power.
If you have a 1394 Power Supply or the included external power supply, connect the
camera as listed
in Step 3 of the “Introduction” Section.
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 EM-C
2
camera ’s sensor.
• Point the camera at something in the far distance. Loosen the set-screw of the C-mount
ring (there are three: one on the side and two on the top). Adjust the C-mount ring until
the image is in focus. Then tighten the set-screw so that the C-mount ring does not move.
A lens is not supplied with the camera.
• 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.
