Abstract
A constant intensity of the interferometer illuminating light is an important contribution for achieving the ultimate accuracy. Separate setups were arranged to investigate means for improving temporal and spatial stability of the light at the entrance of the Avogadro sphere interferometer. The effect of these arrangements on the measurement uncertainty will be demonstrated.
