This process is repeated about a dozen times and the interferograms averaged. The average represents the errors in the transmission sphere and interferometer because the ball is extremely round and the small imperfections of the ball average to zero. The calibration can be done in as little as 10 minutes and the result is difficult to dispute. Best used with low F/# transmission spheres.
