Notes
Depending on the mode of operation, these devices emit highly concentrated non visible infrared light which
can be hazardous to the human eye. Products which incorporate these devices have to follow the safety
precautions given in IEC 60825-1 and IEC 62471.

Glossary
1)
Typical Values: Due to the special conditions of the manufacturing processes of LED, the typical data or
calculated correlations of technical parameters can only reflect statistical figures. These do not necessarily
correspond to the actual parameters of each single product, which could differ from the typical data and calculated
correlations or the typical characteristic line. If requested, e.g. because of technical improvements, these typ. data
will be changed without any further notice.
