Abstract

The Edlén equation has become the standard method of relating the index of refraction of air to the air temperature, pressure and humidity. The recent suggestion for improvements in the humidity dependence by Birch and Downs has been verified at the 0,633 μm He-Ne laser wavelength using the line scale interferometer at the National Institute of Standards and Technology (NIST).
