Remarks concerning optical radiation safety*
For low forward current (<100 mA) and continuous operation, this LED may be classified as LED
product Class 2 , according to standard IEC 60825-1:A2. Class 2 products emit in the visible region,
damaging exposure is usually prevented through avert reactions including blink reflex. It can be
expected that these reactions provide sufficient protection under reasonably predictable conditions.
This also implicates a direct observation of the light beam by means of optical instruments.
When driven with higher continuous forward current, (up to max. DC current), this LED should be
classified as LED product Class 2M , according to standard IEC 60825-1:A2. Class 2M products are
safe to eyes and skin under normal conditions, including when users view the light beam directly.
These products emit in the visible region and it is presumed that the human blink reflex will be
sufficient to prevent damaging exposure, but if the beam is focused down, damaging levels of
radiation may be reached. Therefore, users should not incorporate optics that could concentrate the
output into the eyes.
*Note: Safety classification of an optical component mainly depends on the intended application and
the way the component is being used. Furthermore, all statements made to classification are based
on calculations and are only valid for this LED "as it is", and at continuous operation. Using pulsed
current or altering the light beam with additional optics may lead to different safety classifications.
Therefore these remarks should be taken as recommendation and guideline only.
We reserve the right to make changes to improve technical design and may do so without further notice.
Parameters can vary in different applications.All operating parameters must be validated for each customer application by the customer.
