2.2.2 Cleaning of the CCD
Cleaning of a CCD sensor is a rather difficult task. Depending on the aperture of the lens used, any dust particles
with a size of 10
µ m and larger can show up in your image.
All cameras are checked for cleanliness in our factory before shipment. Proper handling instructions during system
assembly can prevent that the CCD gets contaminated.
Should cleaning of the CCD be necessary follow the instruction below.
Note that damage of the CCD due to scratches on the cover glass, or Electro Static Discharge (ESD) is not
covered by warranty!
The correct working environment for cleaning is essential in order to ease cleaning, and to prevent damage of the
CCD.
Precautions:
• Take precautions to prevent ESD that can damage the CCD sensor
• Cleaning of the CCD, and assembly of the lens is preferably performed in a clean room or clean bench.
• Never try to clean the CCD 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 ESD.
• Be sure to clean the C-mount of the lens before assembly.
• Use non-fluffing Q-tips and Alcohol (or Hexane) for cleaning. De-ionized water may be necessary to remove
ionic contaminants like salts.
• Any Q-tip 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.
Cleaning instructions:
1. 1. 1. 1. First try to remove the contamination by using clean, dry air. (Use an ultra-filtered, non-residue dust
remover spray). Prevent to blow air in the screw thread of the lens mount, because this may cause
contamination on the CCD due to loose particles and traces of oil or grease.
