Cleaning with air
Blow directly on the contaminated surface with moderate pressure, clean com-
pressed air.
View a live image with the camera after blowing. If debris is still present, repeat
the process until it is determined that the particulate cannot be dislodged. If
this is the case, proceed to the contact cleaning technique.
Contact cleaning
Only use this method if the above air cleaning method does not sufficiently
clean the surface. Use 99% pure isopropyl alcohol and clean cotton swabs. Wet
the swab in the alcohol. Quickly wipe the optics in a single stroke. Prolonged
exposure of alcohol on the swab can cause the swab glue to loosen and transfer
to the optic glass. Do not reuse the same swab. Repeat this process until the
debris is removed. If this process fails to remove the debris, contact AVT.
Note
•
A pin spanner wrench (AVT P/N: E9020001) suitable for
IR filter removal is available for purchase from AVT for all
GT cameras except GT4100, GT4905, GT4907, and
GT6600.
•
DO NOT attempt to remove the camera IR filter for
GT4100, GT4905, GT4907, and GT6600
. Please contact
for assistance.
Caution
Do not exceed 90 psi. If using canned air (typically ~ 70 psi
when full), do not shake or tilt the can, as extreme changes
in temperature due to sudden cold air can crack the optic
glass.
