A new resolving power test chart has been made that embodies the features outlined by Dr. Gardner in an earlier report. A contact print of this chart is made with the aid of a small distant light source and a specially shaped diaphragm moving over the chart at constant speed. The final test chart has a continuous variation in contrast from one end of the target line to the other. This chart is to be used to determine the variation of resolving power with contrast for a given lens with a single exposure. The long lines of the target make it especially suitable for microphotometric examination of the final test images, thus bringing closer an objective method of determining the resolving power of a photographic lens.
