Coarse centring and collimating of the Angular Prism
Uncover the mirror by removing the Prism Turret. Coarsely adjust the Angular
Prism adjusting the tripod height and using the Slide Table.
Make a fine adjustment to the Angular Prism using the adjustment screws for
parallel movement in the X and Y directions so that the laser spot hits the
centre of the mirror..
Adjust the reflected beam so it hits the laser aperture on the T220 by using
the tilt adjustment screws on the Angular Prism. Check that the laser beam
still hits the center of the mirror. If necessary, adjust parallel and then
angular again.
