Optical spectrum analyzers directly measure the wavelength of light in an air environment. However, most wavelength measurements are quoted in terms of wavelengths or optical frequencies in a vacuum. This can lead to errors, particularly in DWDM systems, since the index of refraction of air is a function of wavelength, temperature, pressure, and gas composition. The wavelength dependence of the index of refraction n of standard dry air at 760 torr and 15°C is64 2406030 15997 n =1+ 10*| 8342.13 + air 130 – 1 38.9 where 2 is measured in micrometers.
