Operating Instructions
for
Triple Grating Turrets
SP-300i/500i
Ver 2.0
Become familiar with the components as labeled on Figures 1, 2 and 3 in this
section.
2. Scan the instrument to grating #1 and the highest wavelength position.
3. Place the monochromator in a clean, dust free area.
4. Remove the screws from the monochromator access cover and remove the
access cover. Become familiar with the grating turret and its components.
5. Locate a 9/64 ball end hex driver (Bondhus #9/64)*. Refer to Figure #3 and
with the 9/64 ball end hex driver, loosen the turret clamping screw #1.
(NOTE: All 3 turret clamping screws are captive). Loosen the turret clamp
screw #2 and then #3.
6. Use extreme care so as not to touch the grating surfaces and grasp the top
plates of the grating turret, refer to Figure 2. Lift the grating turret straight up
off the grating spindle assembly. If the turret cannot be lifted up, assure the 3
clamping screws are disengaged from the grating spindle assembly.
7. Place the removed grating turret assembly on a clean surface.
8. Remove the plastic cover from the grating turret storage container. Loosen
the 3 grating turret clamping screws. NOTE: These screws are captive.
CAUTION: Do not hit the grating surfaces as permanent damage will be
caused.
9. Carefully grasp the grating turret by the top plates. CAUTION: Do not touch
the grating surfaces. Lift the grating turret out of the storage container.
10.Locate the grating turret # on the grating turret assembly. Assure the
monochromator is as grating #1 and highest wavelength position. Refer to
Figure #1 and place the grating turret on the grating spindle with the turret #
located as shown.
11.Assure the turret is properly seated, the ball in the cone hole and the rod in
the vee groove.
12.Lightly tighten clamp screw #1, then #2 and #3. (NOTE: To assure maximum
reproducibility, the clamping screws must be tightened in this sequence and
to 3 inch pounds of torque.) Tighten screw #1, to 3 inch pounds of torque,
then #2 and #3. The grating turret is now installed.
13.Place the access cover on the monochromator. Replace and tighten the 8
cover screws.
14.Install the removed grating turret into the storage container and tighten the 3
clamp screws. Replace the plastic cover.
