✦ Synopsis

A new method is described for accurately positioning the light source of the ultraviolet absorption optical system of the Beckman Model E analytical ultracentrifuge. This method provides very accurate determination of both the height and radial position. A six-channel centerpiece is used to produce a three-line image on the film. Densitometer scans of exposures made at several positions of the source are used to determine the optimum position.
