4. Measurement uncertainties
4.1 Wavelength uncertainty
4.1.1 Wavelength uncertainty in a vacuum
Measurements of the frequency of many lasers show that there is a certain dispersion around the value entered into the calculator by the manufacturer. This is approximately :
If this uncertainty, which leads to an uncertainty on displacement measurements...
