A unit magnification system is described which is free from Seidel aberrations and which can be used at very high aperture. The leading higher order aberrations are derived.

A method using this system for reproducing photographically small groups of lines with a spacing of 6000 lines/in. is described.

Several other possible applications of the system are outlined.
