12.2 Cleaning
12.2.1 Routine (to be carried out
regularly)
Maintenance frequency will depend on the
type of environment in which the housing
is used.
12.2.1.1 Cleaning the glass
Avoid ethyl alcohol, solvents, hydrogenated
hydrocarbide, strong acid and alkali. Such
products may irreparably damage the
surface.
Surface dirt should be rinsed away with water and
then the window cleaned with a neutral soap diluted
with water, or specific products for spectacle lens
cleaning. These should be applied with a soft cloth.
12.2.1.2 Germanium glass window cleaning
When cleaning the window with the IR filter,
take extra care not to scratch or damage the
outer surface treated with carbon coating.
Damage to this coating could also interfere
with the transparency of the surface to
infrared light.
Surface dirt should be rinsed away with water and
then the window cleaned with a neutral soap diluted
with water, or specific products for spectacle lens
cleaning. These should be applied with a soft cloth.
12.2.1.3 Cleaning the device
The device should be cleaned using a damp cloth;
compressed air must not be used.
