These factors are taken into account for deriving the wavelength for resolved levels of uncertainty (listed
below).
Standard Uncertainties and Uncertainty Budgets in % at Wavelength (Example)
400 500 600 800 1000 1200 1600 1800 2000 2400
Standard uncertainty
k = 1
5,09 3,64 3,01 3,00 3,04 3,04 3,05 3,04 10,86 10,86
Expanded uncertainty
k = 2 10,18 7,28 6,01 6,00 6,08 6,08 6,10 6,08 21,71 21,71
Place the light source horizontally. A value of 6 % of expanded uncertainty must be taken into account for
vertical placement.
