7 ALIGNMENT AND ADJUSTMENT

7.1 Optical alignment

Correct operation of detection depends on barrier alignment.
This alignment consists in lining up the optical axes of the column cells installed facing each other.
This basic alignment adjustment is performed for each cell using the integrated sighting system.
DESCRIPTION OF THE CELL VIEWFINDER
• Loosen the adjusting knob (1) thereby allowing the cell
to rotate horizontally + or - 90º.
• Place the eye in front of the cell along an oblique line of
sight.
• Aiming consists in visualizing the image of the opposite
housing (see figure above) in the internal mirror.
• Aiming is performed by rotating the sight horizontally +
or - 90º by directly manipulating the cell fork (3).
• Vertical rotation + or - 10º via the adjustment knob (2).
• After sighting the image, do not forget to fasten the
adjustment knob (1).
Note : accommodation distance for the eye: approximately 5 cm
