Transmission/Reflection Vs. PMT Angle
1. Ensure all the stages are properly calibrated.
2. Perform the Sample Rotation Optimization subroutine to determine the location of the samples.
3. Set the Sample Rotation to the vacant spot for the reference scan.
4. Set the sample tilt to the desired angle.
5. Set the monochromator to the desired wavelength.
6. Go to the “PMT Rotation” tab and set the scan parameters for the measurements: Start and End Angle; Angle step increment;
# of averages per measurement; the delay between readings (only applies if doing more than one averages); and the PMT
gain.
7. Select the type of scan to be performed: Constant Rate or Fastest Speed. Fastest speed will go through the scan as quickly
as it can under the set parameters; however the time interval between steps may be inconsistent due to software
hand-shaking. Constant rate introduces a delay between steps so that the time interval between steps is conisistent
throughout the scan.
8. When all parameters are set, click the “Start Scan” button.
9. When the scan is complete, record the Scan # for future calculation.
10. Repeat steps 3-9 for each sample to be measured. It is recommended to take additional reference scans either after each
sample or, at the least, after completing all the sample scans to compensate for any potential lamp drift.
11. When ready, set the scan # for the sample who’s transmission/reflection you want to measure as Plot 2 and set two
reference scans (either the ones taken at the start and end of the scan sequence or the ones taken immediately before and
after the scan for desired sample) as plots 3 and 4.
12. Setup the function setting to calculate the transmission/reflection of the sample using the average of the two reference scans
selected.
13. When you’re satisfied with the formula setup, click on the “Calculate Result” button. The displayed graph will automatically
change to the calculated transmission/reflection curve.
14. If the curve is very noisy, you can take the average of multiple data points by setting the number of data point to be used in
the text box to the right of the “Calculate Result” button and click the “Apply Running Average” button above it.
15. Set the File Name and the File Save Path.
16. In the drop box beside the “Save” button select “Result” then click the Save button. This will save the transmission data as
well as all the spectral data used in the calculation. The green indicator light will turn on to indicate that the files as been
saved successfully.
17. If external manipulation of the data is desired, set Post 1, 2, 3 and 4 to the desired scan #’s and repeat the save process but
setting the Save drop box to the Plot number. This will save each scan in its own individual file.
Transmission/Reflection Vs. Sample Tilt
1. Ensure all the stages are properly calibrated.
2. Perform the Sample Rotation Optimization subroutine to determine the location of the samples.
3. Set the Sample Rotation to the vacant spot for the reference scan.
4. Set the PMT to the desired angle.
5. Set the monochromator to the desired wavelength.
6. Go to the “Sample Tilt” tab and set the scan paramaters for the measurements: Start and End Angle; Angle step increment;
# of averages per measurement; the delay between readings (only applies if doing more than one averages); and the PMT
gain.
7. Select the type of scan to be performed: Constant Rate or Fastest Speed. Fastest speed will go through the scan as quickly
as it can under the set parameters, however the time interval between steps may be inconsistent due to software hand-
shaking. Constant rate introduces a delay between steps so that the time interval between steps is consistent throughout the
scan.
8. When all parameters are set, click the “Start Scan” button.

Cross Sample Transmission/Reflection Measurement
1. Ensure all the stages are properly calibrated.
2. Perform the Sample Rotation Optimization subroutine to determine the location of the ends of the vacant spot and samples.
3. Set the Sample Rotation to the vacant spot for the reference scan.
4. Set the sample tilt to the desired angle.
5. Set the monochromator to the desired wavelength.
6. Perform the PMT Optimization subroutine.
