Align Monochromator Mirror B1
1.
Loosen and remove the two screws securing the limit switch to the base. Move the limit switch to
one side so it will not interfere with the installation of the zero order grating Holder tool.
2.
Lock the tool in the ‘open’ position by compressing the spring until the pin can be inserted into the
locking hole in the tool.
3.
Position the zero order grating Holder tool so that the pin in the base of the tool can be inserted into
the rear screw hole where the limit switch was installed and the hole in the tool base is located over
the front screw hole. Position the grating arm in the L-shaped arm of the tool. Push the tool to the
right as shown in Figure 6.3 when tightening the screw.
