Abstract: A lens bench has been developed incorporating a nodal slide and a flat-field indicator which permits the rapid determination of the square-wave flux response of a lens both on and off axis. A synchronously driven test object is used, and a plot of response vs-line number is presented on an oscilloscope. Lenses up to 24 in. in focal length and in. in diameter may be tested.
