Remarks concerning optical radiation safety*
At low forward current (<150 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 1 A), 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,so 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.
If intended to operate at very high continuous current (>1 A), this product has to be (potentially)
classified as Class 3B LED. Class 3B LEDs may have sufficient power to cause an eye injury, both
from the direct beam and from reflections,so these products are therefore considered hazardous to
the eye. However, the extent and severity of any eye injury arising from an exposure to the light
beam of a Class 3B product will depend upon several factors including the radiant power entering
the eye and the duration of the exposure. Nontheless, adequate precautions should be taken to
avoid direct or indirect viewing into the beam.
*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.

Handling precautions
To prevent damage to the LED during soldering and assembly, following precautions have to be
taken into account.
a) The bending point of the lead frame
should be located at least 2.5 mm away
from the body.
b) While bending, the base of the lead
frame has to be fixed with radio pliers or
similar.
c) To ensure an adequate strain relief, the
lead frames have to be firmly fixed during
soldering.
d) Avoid any torsion or tensile loading of
the lead frames, especially when they
have been heated after being soldered.
e) LEDs are static sensitive devices, so
adequate handling precautions have to be
taken, e.g. wearing grounding wrist straps.
