SERVICE & MAINTENANCE
Precautions:
Take general precautions to prevent ESD that can damage the CCD sensor •
Cleaning of the CCD sensor, and assembly of the lens is preferably performed in a clean room or •
at least at a clean bench.
Never try to clean the CCD sensor at a relative humidity lower than 30 %. A relative humidity of •
40 % or higher is preferred in order to minimize the chance of damage due to ESD.
It is advisable to use an ionizer, in order to minimize the built-up of electrostatic charges. •
Use non-fluffing cotton swab and Alcohol (or Hexane) for cleaning. De-ionized water may be •
necessary to remove ionic contaminants like salts.
A cotton swab should be used only once - you will otherwise move dirt from one place to another. •
Never rub the window dry. This may cause static charges or scratches that can destroy the CCD •
sensor.
Cleaning directions:
First try to remove the contamination by using clean, dry air. Use an ultra-filtered, 1.
non-residue dust remover spraycan. Dry air can cause an electrostatic charge. Take
appropriate environmental measurements to avoid the build-up of electrostatic
charges. Prevent blowing air in the thread of the lensmount, because this may cause
contamination on the CCD sensor due to loose particles and traces of oil or grease.
If this step does not result in an acceptable result, continue with step 3. 2.
Remove the lens mount by removing the 4 crosshead screws that hold the lensmount. Clean 3.
the inner side thread of the lens mount using Alcohol or Hexane and a cotton swab.
Clean the CCD cover glass using Alcohol or Hexane and a cotton swab. Gently and 4.
carefully rub the window always in the same direction, e.g. top to bottom.
Install the lensmount back onto the camera. 5.
Check the results of the cleaning operation.
Install a lens and power up the camera. Adjust the lens at a small aperture (f.i. F16) and 6.
point the lens at a bright lightsource. Adjust gain and integration time if necessary.
Check the image on the monitor for dark spots and stripes caused by contamination 7.
on the CCD sensor cover glass. (Note that the image on the monitor should not
saturate due to over exposure - if necessary close the iris even further).
If the CCD sensor is not clean, repeat steps 3 - 7 using a new cotton swab. After three 8.
unsuccessful tries, it is advised to wait a few minutes before a new attempt is made to clean the
CCD sensor. (This allows the electric charge that has been built up during cleaning to neutralize).
If the cleaning operation is not successful, it is recommended that you contact your business office
service department to get the appropriate support.
Maintenance 9.5
No specific maintenance other than cleaning is applicable.
