Camera cleaning
119 Goldeye G Technical Manual V 2.0.0
When mounting or dismounting a camera lens or dust cap, always hold the camera
with the mount opening pointing downwards. This minimizes the possibility of any
contaminants falling on the glass surface.
Always store cameras and lenses with dust caps on.
Identifying contaminations
If small visible dust or contamination particles on glass surfaces can be observed
from the outside, this does not necessarily mean that these particles affect the
functioning and/or application of the camera.
Since these particles are out of focus, they are not likely to have any impact on the
image. An impact on the image may only be given if any particles can be observed
in the video preview of your camera.
The contaminations you observe in the video preview may be situated either on
the lens, on the filter/protection glass, or on the sensor. Contaminations may
develop due to handling or unclean environments, even if your camera has been
cleaned prior to sealing and shipment.
As shown in Figure 30 below, contamination (dust, particles, or fluids) on the
sensor or on optical components may appear as a dark area, patch, or spot on the
image and remain fixed in the preview window while you rotate the camera over
the target.
Also, contaminations that are situated on the edge of the lens and/or the filter,
may not be in the field of view, and therefore won‘t be visible in the image.
