Remarks concerning optical radiation safety*
Up to maximum forward current, at continuous operation, this LED may be classified as LED
product
Class 1
, according to standard IEC 60825-1:A2.
Class 1
products are safe to eyes and skin
under reasonably predictable conditions. This implicates a direct observation of the light beam by
means of optical instruments.
*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.
