• Step 8
If adjustment screws L11 and L12 are too tight, adjustments to A1 and A2 may
not be possible. If this happens, loosen L11 and L12 and proceed to step 9.
• Step 9
If it is observed that the slit image is centered at 546 nm, but is not centered at
0 nm, return to step 1.
If it is observed that the slit image is centered at 0 nm, but is not centered at
546 nm, return to step 3.
• Step 11
If it is observed that the slit image is centered at 546 nm, but is not centered at
0 nm, proceed to step 12, and then return to step 1.
If it is observed that the slit image is centered at 0 nm, but is not centered at
546 nm, proceed as directed to step 12, and then return to step 3.
