Cleaning optical components

Prosilica GC Technical Manual V2.2.0
3.
Hold the camera sensor diagonally upwards. Ensure that the camera is away
from your body to prevent particles like skin flakes from falling on the sensor.
4.
Wipe the glass surface with a spiral motion from the center to the rim.
Normally, several spiral wipes are recommended. Wipe only on glass avoiding
contact to metal surfaces, because microscopic dirt could be released and
could cause scratches on the glass.
5.
When you have finished cleaning, examine the surface in a strong light. Take
an out-of-focus picture of a flat, illuminated surface to see if any dirt or dust
remains.
6.
If dust spots remain, repeat this procedure using new clean lens tissue (as
described above).
Cleaning with compressed air
Allied Vision does not recommend cleaning Prosilica GC cameras with compressed
air.
If you want to clean your camera with compressed air despite of all the warnings:
•
Use an optic approved compressed air product or compressor.
•
Use an anti-static ionizer attachment to reduce the risk of static-caused
damage.
•
Use a filter to remove moisture and oil from the air.
Use short directed bursts of air to remove impurities.
Cleaning issues
If you notice that the camera lens or sensor is not clean after attempting to clean
twice, or if you have any questions regarding cleaning your camera, please contact
your Allied Vision distributor or Allied Vision support.
Possible material damage
•
Compressed air at high pressure and/or shorter operating distances may push
dust into the camera/lens and physically damage the camera, sensor, or
optical components.
•
Propellant from non-optic approved compressed air products may leave a
residue on the camera or lens and may physically damage the camera, sensor,
or optical components.
•
Compressed air may contain oil or moisture that could contaminate or
damage the optical components.
•
Use an air blower/compressed air only if you are familiar with cleaning a
camera using this method.
Compressed air pressure and operating distance
•
Keep the compressed air pressure at a moderate strength only. Pressure at the
nozzle should be less than 1 bar (15 psi).
•
Operating distance from the camera should be 5 to 30 cm.
