Alignment procedure
Correct alignment is crucial for proper operation of the analyzer. The alignment procedure
has to be carried out with utmost care.
1.
Before mounting the alignment kit, make sure that the contact surface between flange
and the alignment kit is clean.
2.
During the adjustment procedure make sure that you have obtained the smallest
possible focal spot and that it is positioned at the very center of the crosshair.
3.
Before remounting the sensors make sure that the contact surfaces between sensors
and flanges are clean.
The aim of the alignment procedure is to provide a collinear optical axis of both receiver unit
and transmitter unit. To do so first align the receiver to the transmitter and then align the
transmitter to the receiver.
To align a sensor, a point light source is mounted to the flange on the opposite side of the
sensor to be aligned, and the alignment optics is mounted to the flange of the sensor. This
flange is aligned by centering the projected image of the point source to the center of the
cross hair of the alignment tool.
