Resolution
In this context resolution means the smallest possible change in distance of the measure-
ment object, which causes a unique change of the output signal. Resolution is higher in the
short range than in the distant range. Small objects can be recognized better in the short
range.
The length of the laser line in the X-direction is dependent on the distance Z of the measure-
ment object from the sensor . Always the same number of measurement points is measured.
From this it follows that the resolution in X-direction decreases with increasing distance in
Z-direction.
The following illustration shows this relation:

The output resolution of the measurement values on the process interface is 1/10mm with
Standard-Connect, 1/100mm with HI-Connect (only with LES 36HI/VC6).
