Remarks concerning optical radiation safety*
At low forward current (<250 mA), and 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.
When driven with higher continuous forward current, (up to max. DC current), this product should be
classified as LED product Class 1M , according to standard IEC 60825-1:A2. Class 1M products are
safe to eyes and skin under normal conditions, including when users view the light beam directly.
Class 1M products produce either a highly divergent beam or a large diameter beam. Therefore only
a small part of the whole light beam can enter the eye. However, such optical products can be
harmful to the retina if the beam is viewed using magnifying optical instruments. 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.
