Object sizes
As the distance from the device increases, the laser beam expands. As a result, the
diameter of the light spot on the surface of the object increases.

Values required to calculate the light spot size:
•
Light spot size on the device cover: 7 mm (rounded up)
•
Divergence of 1 light spot: 0.59 deg (10.4 mrad)
•
HDDM+ supplement (1 spot comprises several superimposed individual pulses):
0.50 deg (8.7 mrad)
Formula for calculating the light spot width:
