The Infra-Red system was tested for its maximum emission produced during working operation and the following results obtained:
On a non reflective surface, i.e. FR4 substrate, if one's eye is placed 150mm away looking down at an angle one could be subjected to approximately 0.9mW/cm2 at full power.
On a reflective surface, i.e. polished aluminium at a normal distance of 300mm, one would be subjected to approximately 0.9mW/cm2.
