Vision prompts the user to rotate the Certified
99% Reflectance Reference. Rotate in 90-degree
increments, for a total of four scans, at the
prompts. The four spectra are averaged, and the
averaged spectrum is used for Reference
Standardization. This minimizes the directional
effects of the standard, to provide best
consistency.
Vision requests the Standard File for the Certified
99% Reflectance Reference. This file is on the
diskette (or Mini-CD) packed with the standard,
and may be copied to the Vision directory for ease
of use. It is shown here on the D: drive, on a Mini-
CD.
The file is named “RSSPxxxx.da”. Click on the file,
then click “Open”.
This is a plot of the un-calibrated
sample fiber in the instrument. (The
plot color is cyan, which is made
darker and “heavier” here for
readability. The spectrum will be
plotted in 1-pixel width on the user
screen.)
The wavelength scale is 800-
2100nm, the scale of this process
instrument.
Click “OK” to plot a spectrum of
the Certified 99% Reflectance
Reference.
