There are 4 report types available, please choose the best suitable for your application (in "MC:
Application Designer"). By "Spectra" the measured spectra are visible.

5.12. Extended Wavelength Range

Commonly the NIR spectral range is defined from 780

– 2’500 nm (appr. 12'800 – 4'000 cm

-1

). The

accessible default range for NIRFlex N-500 is 1'000

– 2'500 nm or 10’000 – 4'000 cm

-1

for all

measurement cells except Solids Transmittance. Solids Transmittance has a default range of 870

– 1660

nm

(11’520 – 6000 cm

-1

).

In both cases, the range can be expanded up to 820 nm (12200 cm

-1

), although there is usually no benefit

from using the extended wavelength range for normal applications. However for some applications
(coloured samples, thick samples) there can be advantages, and it might be worthwhile to test the
extended range for such samples, if no reasonable calibration could be developed using the default range
of the NIRFlex N-500.

Please create a new usergroup e.g. "Superusers" first.

Select: Security Designer => Users and Groups => New User group and create the new group.
