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. %
