Constants and correlations for air. Wavelength correction due to medium dispersion.
Converts wavelength as seen in air to wavelength as seen in vacuum.
wavelength (array-like (nm)) – wavelength in air
wavelength – wavelength in vacuum
- Return type
Not exactly true, as air_index_dispersion is defined for vacuum wavelength However, air_index_dispersion doesnt vary much on 1-2 cm-1 (which is typical of air index dispersion effect on air/vacuum wavelength in the mid-IR)
Estimate the error you make with:
Return air index dispersion as a function of wavelength with the relation of Ciddor 1
lbd (array-like (µm)) – wavelength
Standard air: dry air at 15 °C, 101.325 kPa and with 450 ppm CO2 content
