The LabRail calibration is now finished and have been stored in the flash memory of
the LabRail so no future calibration is necessary unless the system is moved.
You can now click ‘F inished ’ .
From this point on, whenever you want to set a new measurement distance just click
on the
“Sensor distance ” label in Viso Light Inspector software as shown below.
Type the desired distance and the sensor will move to this position.
Finally, you should set the sensor distance to 2 m and re-adjust the sensor height, so
the spectrometer sensor is in the vertical center of the goniometer as shown below.
For mechanical reasons, the laser module in the sensor is slightly offset vertically in
comparison with the actual spectrometer sensor position. During factory sensor
calibration, all spectrometer sensors are aligned to the laser beam at a 2 m distance.
This will give some sensor positioning errors when measuring above or below 2 m
