Nominal ocular hazard distance

The installation setup must prevent access to the nominal ocular hazard area. Failure to
comply results in death or serious injury.
The nominal ocular hazard distance (NOHD) is the distance from the projector where the light
intensity becomes lower than the maximum permissible exposure (MPE) on the eye. Perform NOHD
calculations on site or after final configuration as it is dependent on power level and lens option.
Emitted light from the projector is an extended source. The table lists sample NOHD.
