08 Camera Maintenance
1. Drying the CCD Chamber
The CCD sensor is located in a CCD chamber. This chamber is airproof and connect to the
socket of the silicone gel tube on one side of the QHY367C front case. If there is moisture and
cause the CCD sensor glass get dew. You can connect the silicone gel tube on the socket to dry
it.
Please put the effective silicone gel into the silicone gel tube. Make sure there is a small
amount of cotton inside to prevent the silicone gel get into the CCD chamber.
2. Avoid CCD chamber optic window get dew
If the environment humidity very high, the optic window of the CCD chamber may get dew. The
QHY367C has the build-in heat board on this optic window to heat the optic window to avoid it.
In most conditions it can take effect.
If the optic window still get dew please try the following method.
1.
Avoid the CCD Camera face down to ground. The cold air is heavy than warm air, if you put
the camera facing down to the ground, the cold air is easy to get the optic window and
cause it very cold and get dew
2. Increase the temperature of the CCD sensor. You can increase the CCD sensor temperature
a little to prevent the optic window get dew.
3. Check if the heat board working. If the heat board not working, the optic window is easy to
get dew. Normally the heat board can get about 65-70C in +25C environment. If it is not so
warm, it maybe the problem of the heat board damaged. Need to contact QHYCCD to
replace one heat board.
