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.
