Laser Product Classification
All Options UH1, UH2, URU, USN, 130, 131 and UKT are classified as
Class I (non-hazardous) laser product in the USA which complies with
the United States Food and Drug Administration (FDA) Standard 21
CFR Ch.1 1040.10. Options UH1 and UH2 are classified as Class 1 (non-
hazardous) laser products in Europe which complies with EN 60825-1
(1994).
Options URU, USN, 130 and 131 are classified as a Class 3A laser
product in Europe, which complies with EN 60825-1 (1994) / IEC825-
1(1993).
Laser classification is based on the ability of the optical beam to cause
biological damage to the eye or skin. The EN 60825-1 (1994) definition of
Class 3A is:
”Any laser product which permits human access to laser radiation in
excess of the accessible emission limits of Class I and Class 2 as
applicable, but which does not permit human access to laser radiation in
excess of the accessible emissions of Class 3A and Class 3B (respectively)
for any emission duration and wavelength.”
Options URU, USN, 130 and 131 fall into this category, under the EN
60825-1 (1994) (European) standard, because they have a maximum
output power of 19.5 mW (under fault conditions), with a wavelength of
1550 nm.
To avoid hazardous exposure to laser radiation, it is recommended that
the following practices are observed during system operation:
• ALWAYS DEACTIVATE THE LASER BEFORE CONNECTING
