[t] Uncertainties derived from rGD uncertainty and from
\
2 pm relative wavelength uncertainty for
Δλ
between 0.1 nm and
10 nm. Parameters and conditions as for rGD.
[u] Wavelength resolution
Δλ
equals (wavelength increment
∗
selected smoothing width) (see manual). Valid for
Δλ
between 0.1 nm and 10 nm.
[v] Typical without wavelength meter option. (
\
0.006 nm with wavelength meter option.)
[w] For fibers. Determined by a curve fit over a wavelength range of 10 nm including the zero-dispersion wavelength, with
wavelength increment
≤
1 nm, assuming that the selected curve fit sufficiently represents the fiber dispersion curve (the fit
does not contribute to the error).
[x] Method confirmed on NIST Standard Reference Material 2524.
