Hazard Distance for fully closed projection system
HD
Hazard Distance (HD) is the distance measured from the projection lens at which the intensity or the energy per surface
unit becomes lower than the applicable exposure limit on the cornea or on the skin. The light beam is considered (to
be) unsafe for exposure if the distance from a person to the light source is less than the HD.
Restriction Zone RZ Based on the HD
The projector is also suitable for rear projection applications; projecting a beam onto a defuse coated projection screen. As displayed
in image 1-3 two areas should be considered: the restricted enclosed projection area (RA) and the observation area (TH).
