1. Safety
restricted zone of the projected beam toward the screen; taking into account 1 meter Separation Width (SW) from the beam onward.
Combined with the restricted zone related to the rear re
fl
ection from the screen (HD
re
fl
ection
); also taking into account a 1 meter lateral
separation.
The HD
re
fl
ection
distance equals 25% of the difference between the determined HD distance and the projection distance to the rear
projection screen. To determine the HD distance for the used lens and projector model see graphs in chapter "HD in function of
modifying optics", page 10.
HD

= 25% (HD – PD)
The light emitted from the screen within the observation shall never exceed the RG2 exposure limit, determined at 10 cm. The
HD
diffuse
can be neglected if the measured light at the screen surface is below 5000 cd/m² or 15000 LUX.
