Manual Est.
Allows users to adjust the following values:
Beginning/Ending Wavelength/Energy:
The wavelength/Energy range is the range of light spectrum that
is being measured to produce a reading. SpecMetrix® software currently measures in 3 different spectral
ranges:
•
Visible spectrum (VIS) which ranges from 400 nm – 1000 nm (can also detect in the 200-400nm
wavelength region if a UV light source is included).
•
Near-Infrared (NIR) which is from 900 nm – 1700 nm.
•
Extended Range (ER) which operates in the 485-1300 photon energy range.
When you adjust, the wavelength or Energy ranges you are narrowing the available spectrum in which is
measured. This becomes apparent in the Spectral graph as you slide the Start or End wavelength indicator.
Index of Refraction (IOR):
Changing the IOR will not change the wavelength or wave graph but will have
a direct impact on the peak graph and the resulting thickness.
Height (Height Threshold):
This is the minimum amount of height (distance from the bottom point to the
top point for a given interference cycle) required to consider the interference wave as valid. If the peak to
valley distance is less than the height threshold value, then that is not considered as a valid interference
cycle. A typical value for this field is from 0.002 to 0.01.
Estimated Microns:
The estimated thickness of the material at a specific point on the graph
Estimated Conversion Factor:
The conversion rate to convert from microns to another unit of thickness
or weight.
