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.
The Certified 99% Reflectance
Reference is shown with the sample
channel spectrum, acquired against the
internal instrument reference fiber. (Plot
color is red.)
The wavelength scale is now wider,
because the Certified 99% Reflectance
Reference has a spectrum from 400-
2500nm. The sample fiber spectrum
(top) is still plotted 800-2100nm.
After Reference Standardization, the
upper spectrum will be corrected to
look like the lower spectrum. Click “OK”
to plot a correction spectrum.
