Resolving problems with the camera
The white LED is not lit
• Check all the cable connections.
• Flip 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
EXi Aqua 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.
• 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 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 "un-sharp" image, contact your microscope dealer to assist you in
finding the most appropriate coupler.
