Maintenance and Repair
Power too high, camera saturated!
Explanation
Some pixels within the selected ROI or Calculation Area are saturated
because they reach the maximum digit value (255 in Fast Mode (8 bit data)
and 4095 in Precision Mode (12 bit data)). Therefore, the local beam intensity
may be even higher than displayed. Calculated beam parameters cannot be
calculated correctly!
Resolving
Decrease Exposure Time and Gain settings or reduce the beam intensity
using a higher attenuation ND filter of the
. You may also
cascade two filters.
If automated Exposure Control is activated, a short appearance of this error is
harmless because Exposure Time and Gain will be reduced automatically
Power too low!
Explanation
The brightest pixel values fall below 10% of the available saturation range. This
means that 90% of the available range remains unused. Therefore,
measurement noise is increased by digitizing noise.
Resolving
Increase Exposure Time and Gain settings or increase the beam intensity
using a lower attenuation ND filter of the
. You may also remove
the filter.
High ambient power level!
Explanation
The lowest pixel value within the selected camera ROI or Calculation Area is
too high. Therefore, the beam edges cannot be detected or distinguished
from a constant ambient light level. The reasons are either the laser beam
diameter is wider than the chosen ROI or the ambient light is too high.
Calculated beam parameters cannot be calculated correctly!
Resolving
Choose a larger ROI so that its height and width is at least twice the beam
diameter.
Reduce the influence of ambient light by proper shielding or select a higher
attenuation out of the
and increase the beam power.
Attention
Calculation results are not reliable as long as an error or warning is
displayed within the status bar!

Cleaning
Since the protective glass window was removed from the camera sensor to prevent
optical interferences it has become extremely vulnerable!
Removing dust from the naked sensor chip can only be done using compressed gas
which is free from oil and water. Thorlabs duster spray (Tetrafluoroetane) can be
recommended. Keep the gas nozzle at least at a distance of
4 inches (10 cm)
