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 mini-
mize any possible eye hazard:
- Use lowest possible drive level
- Use diffusing optics where possible
- Avoid staring into powerful emitters or connected fibers
