Warning:
This data sheet refers to high power infrared emitting semiconductors.
Depending on operating conditions (drive current, pulse duration, optics, etc.) they may emit
luminance/radiance levels considered harmful to the human eye, acc. to IEC 825.1.
When operating powerful emitters, care should be taken to comply with IEC 825.1 to minimize
any possible eye hazard:
– Use lowest possible drive level
– Use diffusing optics where possible
– Avoid staring into powerful emitters or connected fibers
