Microscope with a magnification range about 50X up to 300X
A microscope can be found in most photography stores, or can be
obtained through or specialist mail order companies. Special fiber-scopes
are available from suppliers of splicing equipment.
Ideally, the light source on your microscope should be very flexible. This
will allow you to examine your device closely and from different angles.
A microscope helps you to estimate the type and degree of dirt on your
device. You can use a microscope to choose an appropriate cleaning
method, and then to examine the results. You can also use your
microscope to judge whether your optical device (such as a connector) is
severely scratched and is, therefore, causing inaccurate measurements.
Ultrasonic bath
Ultrasonic baths are also available from photography or laboratory
suppliers or specialist mail order companies.
An ultrasonic bath will gently remove fat and other stubborn dirt from your
optical devices. This helps increase the life span of the optical devices.
Only use isopropyl alcohol in your ultrasonic bath, as other solvents may
damage.
Warm water and liquid soap
Only use water if you are sure that there is no other way of cleaning your
optical device without corrosion or damage. Do not use hot water, as this
may cause mechanical stress, which can damage your optical device.
Ensure that your liquid soap has no abrasive properties or perfume in it.
You should also avoid normal washing-up liquid, as it can cover your
device in an iridescent film after it has been air-dried.
Some lenses and mirrors also have a special coating, which may be
sensitive to mechanical stress, or to fat and liquids. For this reason we
recommend you do not touch them.
If you are not sure how sensitive your device is to cleaning, please contact
the manufacturer or your sales distributor.
