2 Guidelines for selecting the protective device
Once the hazards have been assessed appropriately, there are at least three essential
features to consider when selecting a safety light curtain:
1.2.1 Resolution
The device’s resolution is understood to be the minimum size that an opaque object must be
to safely interrupt at least one of the beams that form the area of the protected field.
The resolution is closely linked to the part of the body that requires protection.
R =
14 mm Finger protection
Type 4
R = 30 mm Hand protection
Type 4
As
shown in Fig. 1, the resolution depends solely on the geometric properties of the lenses,
the diameter and the distance and so is unaffected by the light curtain’s ambient and
operating conditions.

The
resolution value can be calculated using the following formula:
R
= I + d
where:
I = Distance between two adjacent lenses
d = Lens diameter
