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.
