3.7 CLEANING NECTA CAMERA
Each NECTA camera is carefully cleaned and checked before shipment. Nevertheless, using the camera
in unclean environments may let dust enter the optical path. Since cleaning procedures require time
and care and can be performed by trained personnel only, the best way of keeping your camera clean
is avoiding extraneous matters enter the camera. Improper cleaning procedures may damage camera
components. Contact Alkeria SRL if you are not familiar with the procedures described below. Any
damage to sensor, lter, protection glass and camera housing occurred during cleaning procedures is
not covered by Alkeria SRL warranty.
3.7.1 Before starting
Risk of electric shock
Disconnect USB cable from the camera.
Disconnect the I/O cable, if present.
Wear ESD-safe clothes and operate in an ESD-safe environment to avoid dam-
aging the camera (never use synthetic clothes or insulating chairs).
Discharge yourself by touching a conductive grounded surface before han-
dling the camera.
3.7.2 Cleaning NECTA camera housing
• Keep lens mount hole sealed (using a lens or a proper cover) when cleaning camera housing.
• Use only a soft, dry cloth.
• In case of persistent spots, use a soft cloth with few drops of optical grade cleanser or neutral
detergent, then dry quickly.
• Never use cleansers such as gasoline, spirits or solvents. Aggressive products may damage the
camera housing surface.
3.7.3 Optical path cleaning
• Perform the cleaning procedure of any optical component in a dust-free clean environment.
• Avoid directly touching optical parts with bare ngers. Wear clean-room grade latex or nitrile
powder-free gloves.
• Avoid touching any optical surface with rough materials.
• Use only optical grade wipes, not to leave dirt residues and to scratch the glass. Never use com-
mercial grade cotton swabs.
• Use only low residue optical grade cleansers, this avoids haloes over the glass.
