A critical method of focusing an optical diffractometer

A simple but critical method of focusing the optical diffractometer is described. It depends on certain features in the intensity distribution near the focus in an error-free diffraction image of a circular aperture. Minor modifications to the optical diffractometer necessary to permit the application of the method are indicated.
