Cleaning optical components

Goldeye G/CL Technical Manual V4.1.1
Cleaning instructions
Carry out all cleaning operations (on lenses, filter or protection glass, and sensor)
in a
clean dust-free room
. The optical components are very fragile; therefore you
must not touch them with your fingers or any hard material.
1. Unplug the camera from any power supply before cleaning.
2. Have the cleaning materials ready before you start the cleaning.
3. Apply a small amount of cleaning liquid to a clean, new lens cleaning pad or
tissue.
The pad or tissue should be moist, not dripping. Hold the camera away from
your body to avoid that particles like skin flakes fall onto the sensor. The
camera front should point roughly 45 degrees upwards.
4. Wipe the glass surface in either one of two ways described below to ensure
any dirt present on the surface be moved to the edge of the 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 sur-
faces, because microscopic dirt could be released and could cause
scratches on the glass.
Use proper cleaning materials when cleaning glass surfaces.
•
Never
wipe lenses with dry swabs or tissue - this may cause scratches.
•
As a cleaning tool,
use only
lens cleaning tabs or a lens cleaning tissue
wrapped around a small piece of plastic. The lens cleaning tissue must be
chemically pure and free from silicones and other additives.
•
Do not use
metal tools.
•
Do not use
any disposable cotton cosmetic swabs; they may contain
contaminants.
•
Do not use
cosmetic cotton.
•
Do not use
consumer eyeglass cleaning cloths pretreated with silicone.
•
Do not use
fibrous material that may get caught in small gaps.
•
As cleaning liquid,
use only
optics cleaner (60% ethyl alcohol, 40% ether) or
isopropyl alcohol.
Never use
aggressive cleaners like benzine or spirits. Using cleaners like that may
damage the surface.
