Visible Grating.  %

Align the HeNe as perpendicular as possible to the monochromator entrance slit.  %

Move the grating angle until the HeNe falls on the exit slit.  %

Shine a flashlight through the entrance slit and observe the colour on the exit slit: if white,
then you are at 0-order (0 nm), if red, then you are at 1st order (632.8 nm).  %

Go to 0-order, narrow the slits, and slowly adjust the angle until the HeNe is going through the
exit slit.  %

Go to Jovin Yvon/utilities and find the motor configuration program.  %

In the Gratings tab, select the 1st grating (1200 line density) and hit Calibrate.  %

In theoretical wavelength, enter 0 nm.  %

In experimental wavelength, enter the wavelength you observe from the control program.  %

Hit set. %
