What do I need for proper cleaning?

Some Standard Cleaning Equipment is necessary for cleaning your 
instrument. For certain cleaning procedures, you may also require certain 
Additional Cleaning Equipment.

Standard Cleaning Equipment

Before you can start your cleaning procedure you need the following 
standard equipment:

Dust and shutter caps

Isopropyl alcohol

Cotton swabs

Soft tissues

Pipe cleaner

Compressed air

Dust and shutter

caps

All of Agilent Technologies’ lightwave instruments are delivered with 
either laser shutter caps or dust caps on the lightwave adapter. Any cables 
come with covers to protect the cable ends from damage or 
contamination.

We suggest these protected coverings should be kept on the equipment at 
all times, except when your optical device is in use. Be careful when 
replacing dust caps after use. Do not press the bottom of the cap onto the 
fiber too hard, as any dust in the cap can scratch or pollute your fiber 
surface.

If you need further dust caps, please contact your nearest Agilent 
Technologies sales office. 

Isopropyl alcohol

This solvent is usually available from any local pharmaceutical supplier or 
chemist's shop.

If you use isopropyl alcohol to clean your optical device, do not 
immediately dry the surface with compressed air (except when you are 
cleaning very sensitive optical devices). This is because the dust and the 
dirt is solved and will leave behind filmy deposits after the alcohol is 
evaporated. You should therefore first remove the alcohol and the dust 
with a soft tissue, and then use compressed air to blow away any 
remaining filaments.

If possible avoid using denatured alcohol containing additives. Instead, 
apply alcohol used for medical purposes. 

Never try to drink this alcohol, as it may seriously damage your health.
