5.2 Installation height and pitching angle
5.2.1 Relationship between installation height and effective working distance
The ranging laser light spot emitted by the AS-11C is rectangular, and the divergence
angle in the vertical direction is different from the horizontal divergence angle. The
divergence angle in the horizontal direction is 10mrad, and the divergence angle in the
vertical direction is 2mrad, with the increase of the detection distance, the light spot
increases gradually, and its lower edge extends downward gradually. If the ground is hit or
the installation surface is installed, a further target cannot be detected. Therefore, there is
a certain relationship between the effective working distance of the AS-11C and the
installation height, as shown in "Figure 5.1 the relationship between the effective working
distance and the installation height”.
Taking the horizontal floor installation as an example, the relationship between the
bottom installation height h of the AS-21C and the effective working distance d'
max
is:

Important Tips
The actual installation height of the AS-11C should be
determined according to the requirements of the relative
height and working range between the ground of the work
site or the base working face and the installation position.
