Abstract

By means of a tele-objective system in a test collimator, which includes a tilted test plate with appropriately proportioned Foucault groups, it is possible to examine cameras of different focal lengths and still without any mechanical modification to them. The procedure gives the tangential and radial resolving powers, and at the same time the corresponding image surfaces. Distortion may also be determined from the same test photograph.
