Laser Safety Summary
The microscope is fitted with safety filters, which greatly reduce the risk of eye damage due to accidental exposure to red or
infrared light. Always observe eye safety procedures compliant with your company policy, relevant laser safety standards, and
safety practices.
NOTE: It is accepted safety practice to avoid viewing active optical fiber signals. In potentially risky situations, always check for
the presence of light before viewing, using a Ge, InGaAs or high power optical power meter set to its least sensitive practical
setting (often 850 nm).
This microscope is 100% eye safety tested during
production using traceable instruments to the
maximum input power, according to IEC 60625-
2 Ed. 3.2:
640 - 680 nm: 60 mW / 18 dBm (visible red)
680 - 1700 nm: Class 3B (infrared)
The IEC 60825 eye-safe emission limit is either Class
1 or 2. Sometimes it may be desirable to check filters
integrity. There are two safety filters installed-red and infra-red. The infra-red filter is integral with the coaxial illumination, so if
it’s physically damaged, the illumination will not work. Red filter integrity can be easily checked by pulling off the eyepie
ce. A
further check would be to perform an attenuation test using a large area detector against the eyepiece.
Pass/fail Acceptance Guidelines
Proper guidance on pass/fail criteria is beyond the scope of this manual, since it is likely to vary significantly.
The Standard ISO/IEC14763-3 Testing of optical fibre cabling specifies requirements and visual standards for connector end
face inspection with a microscope.
The standard and common industry practices recommend the following pass/fail acceptance criteria:
•
Markings on the core or damage to the cladding close to the core are unacceptable.
•
Slight scratches and small pits on cladding, away from the core, are acceptable.
•
Cracks are not permitted in either core or cladding.
Care of Your Instrument
This is a precision optical instrument. Keep it clean, dry and do not drop. Avoid exposure to moisture or excessive vibration.
Objective and eyepiece lenses should be cleaned with a microfiber cleaning cloth. During prolonged storage, remove battery
to eliminate the possibility of acid leakage.
