Paper Abstract

A project focuses on solving the problem of wavelength measurement of mercury lamps has been established, mainly in the air. Using the Fourier transform method, mercury lamp wavelengths are measured with high-precision, better than 0.1pm. By tracing back to the wavelength of the laser, the measuring device was calibrated very carefully using series frequency stabilized Lasers. The measurement uncertainty is better than 5pm (k=2), in the wavelength range of 250nm to 1100nm.
