Fine centering of the Angular Prism
Attach the FD15 (the centering Detector) on the Angular Prism turret and turn
on its power. The LED flashes green light when turned on, and not reading
any laser spot. When the laser beam hits the detector surface the light turns
to permanently green or red. Rotate the turret so that the color marks are on
each side (left – right).
The LED on the FD15 is now permanently green or red. Green light indicates
that the Angular Prism needs to be adjusted horizontally, e.g. moved towards
red and vice versa. Use the adjustment screws on the side of the turret for
adjustments horizontally. The moment when the light turns from red to green
or green to red, the correct position is reached.
Rotate the turret 90 degrees, color marks at top – bottom. Repeat the above
procedure. Use the adjustment screw for vertical movements until the LED
changes color.
Repeat step 2 and 3 if necessary.
Check that the laser beam is reflected back to the laser aperture on the
T220.
Replace the FD15 with the Angular Prism head.
