1.8.2 Sensitivity and gain factor (Laser Sensor Gain)
The gain factor set depends on the workpiece to be measured (material, surface condition). This setting increases
the sensitivity of the laser scanner during data acquisition. Depending on the measuring result, it may be useful to
adjust the gain factor in the measuring software.
INFORMATION
The gain factor setting significantly affects the quality of the recorded measuring data. If data quality is poor,
adjusting the gain factor can improve data quality. The following gain factor settings are recommendations and
can be adapted to individual ambient/material conditions.

INFORMATION
If the acquisition of measuring data is difficult when scanning dark, shiny or transparent surfaces, the gain factor
should be set to one of the settings "4" or "5".
However, this setting, and the resulting higher sensitivity of the laser scanner, increases the probability of
recording low quality data.
In order to automatically filter out this data from the measurement, the quality filter can also be activated.
1.8.3 Quality filter
The quality filter is used to filter out low quality measuring points from the measurement.
The following quality filters are used here:
• Error data filter for 3D data
• Angle filter
• Outlier filter
• Edge filter
INFORMATION
If the acquisition of measuring data is still difficult when scanning dark, shiny or transparent surfaces, despite
setting the gain factor to "4" or "5", the quality filter should be deactivated.
However, this setting reduces both the measuring accuracy of the system and the data quality.
