The distance-dependent beam expansion can be calculated using the formula: Beam
diameter = (distance (mm) × 2.8mrad) + 40mm

.
The following table shows some example values:
Table 6: Beam diameter at different distances from the device
Distance [m] 5 10 15 20 25 30 40 50 60 70
Beam diameter
[mm]
54 68 82 96 120 124 152 180 208 236
When assessing whether the laser beam can hit an object or the wall, the distance
from the half beam diameter to the optical axis is used.
NOTE
Take into account a supplement of approx. 5mm per meter at the top and bottom.
