Cleaning instructions
Note

Dark spots on the image, especially at nearly closed aperture,
are mostly caused by dust on the sensor of the camera.
Allied Vision Technologies GmbH cleans the sensors around the
lens mount thread with pure air in a clean room class 1000.
After a careful test in the clean room a seal is affixed on the lens
mount aperture.
To receive a dust-free overall system the opening of the seal
and the fitting of the optic should also be done in a dust-free
environment (clean room class better than 1000).
Therefore also a dust-free optic is necessary or rather the optic
has to be cleaned with pure air first.
If, despite of all precaution, dust is on the sensor, the sensor-
area should be blown out with pure air. Therefore compressed
air aerosols are suitable (dust-off-sprays), e.g. Druckluft 76
from CRC Industries, D-76473 Iffezheim, Tel.: 0049-7229-
3030.
When using the air-sprays pay attention that the sprays are not
moved or shaken. Otherwise it comes to an emission of fluid
(propellant).
Caution

Do not touch the sensor with tough objects. The glass is often
scratched and the sensor gets damaged.
