Remarks concerning optical radiation safety*
Up to a forward current of 85 mA, 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.
If intended to operate at higher continuous current, this product would 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, so only a small part of the whole
light beam can enter the eye. However, these LED 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.
