Object size
Light spot divergence
As the distance from the device increases, the laser beam expands. As a result, the
dimension of the light spot on the surface of the object.

Characteristic
Value
Light spot divergence
2.1 mrad (horizontal) x 65.4 mrad (vertical)
Light spot size on the front screen of
the device
0.25 mm (horizontal) x 8.0 mm (vertical)
Light spot size at a distance of 25 m
0.05 m (horizontal) x 1.64 m (vertical)
Formula for calculating the light spot width:
Light spot divergence [rad] x Distance [mm] + Light spot width at the n device cover
[mm] = Light spot width [mm]
Formula for calculating the height of the light spot:
Light spot divergence [rad] x Distance [mm] + Light spot height at the n device cover
[mm] = Light spot width [mm]
This results in a light spot size of 52.8 mm x 1643 mm for a distance of 25 m, for
example.
The high angular resolution and the 24 layers enable scans that have practically no
gaps.
At a distance of 25 m, the distance between tow light spots in the horizontal axis is only
roughly 1 mm. Each light spot is detected by 6 receive diodes, whereby 6 measuring
points are produced per light spot.
Due to the angular resolution of 0.13°, 924 measuring points are detected per layer in
a scan (120°).
