Maintenance
When spraying compressed air, hold the can upright. If the can
is held at a slant, propellant could escape and dirty your optical
device. First spray into the air, as the initial stream of
compressed air could contain some condensation or propellant.
Such condensation leaves behind a filmy deposit.
Please be friendly to your environment and use a CFC-free
aerosol.
Additional cleaning equipment
Some Cleaning Procedures need the following equipment, which
is not required to clean each instrument:
• Microscope with a magnification range about 50X up to 300X
• Ultrasonic bath
• Warm water and liquid soap
• Premoistened cleaning wipes
• Lens papers
• Polymer film
• Infrared Sensor Card
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
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.
