10.
Rotate the camera. Up to 4 degrees of rotation is possible.
The observed peak will go from broad to narrow and back to broad. The camera is
rotationally aligned when the observed peak is at its narrowest.
NOTE:
The system may also be rotationally aligned using the
following alternative method:
1.
Acquire an image.
2.
Display the horizontal and vertical cursor bars.
3.
Compare the vertical bar to the line shape on the screen.
4.
Rotate the detector until the line shape on the screen is
parallel with the vertical bar.
11. After completing the rotational alignment, tighten the four mounting plate screws.
6.8 Focus the System
This procedure requires familiarity with the location of:
•
The mounting plate;
•
The micrometer compartment; and
•
The locking set screw.
REFERENCES:
Refer to the IsoPlane User Manual supplied with the
spectrograph for complete information.
Perform the following procedure to focus the NIRvana-LN with an IsoPlane SCT-320
spectrograph:
1.
Remove the cover from the Micrometer Compartment.
2.
Use a 3/32” hex wrench to loosen the locking set screw.
3.
While continuously acquiring data, adjust the micrometer until the intensity level of a
selected peak or peaks is maximized.
4.
Tighten the locking set screw.
5.
Replace the Micrometer Cover onto the spectrograph. Replace and tighten all cover
screws.
6.
Halt data acquisition.
7.
If the
Shutter Control
setting has been set to
Disable Opened
, change it back to
Normal
at this time.
