Lens Cleaning
Clean the infrared lens carefully. The lens is designed
with refi ned anti-reflection coating.
Don’t clean with force to prevent damage of the anti-
reflection coating.
Please use cleaning solution for lens maintenance
such as alcohol-containing commercial lens cleaning
solution, alcohol or isopropanol as well as a piece of
lint free cloth or paper tissue.
The compressed air tank or dry nitrogen ion gun
(if apply USB cable) may be used to blow the loose
particles on the lens surface.
Dip the lint free cloth in alcohol.
Squeeze the excessive alcohol in the cloth or apply the
lint free cloth on dry cloth lightly.
Wipe the lens surface by making circular motion. Then
discard the cloth.
