Resulting in:

The root is defined as the uncertainty of spectral distribution Spec_Dist. The values are listed below.

Caption for nomenclature of variables:

Variables:
I: Absolute Irradiance [W/cm^2/nm]
R: Percentage of total irradiance in a wavelength Band B

Suffixes:
_B: Wavelength band as defined for spectral match test
_G: Wavelength band of 400 nm to 1100 nm
_Rel: Relative value of variable

Prefix:

Δ: Uncertainty

NOTE:

Values for uncertainties of stray light are not given. For Dark and TEC, see

Nonlinearity Correction and Calibration

.

Uncertainty of Repeated Measurements

Ocean Optics has tested the uncertainty of repeated measurements together with several manufacturers of
Solar simulators. The uncertainty for spectral match test can be rated to be lower than 0.02 % for each
spectral band.

Quantitative Uncertainties

The following quantitative values for uncertainties can be found when the above described sources of
uncertainty are taken into account.
