6.2 Measure
This routine measures the spectrum of your test device and performs the following calculation:
Reflectivity:
substrate
Meas D
R R
Ref D
−
= ⋅
−
As a result you get the theoretical reflectance (or transmittance) of your coated substrate.
If you are using a SCOUT-recipe the measured data are transferred to SCOUT. This takes some time ….
With:
Meas = measured spectrum
Ref
= reference spectrum
D = dark spectrum
R
Substrate
= reflectivity of an uncoated substrate
