Abstract
A molybdenum/silicon multilayer-coated 1:1 ring-field optic with a num erical aperture of 0.0835 is used to carry out soft-x-ray projection i maging with undulator radiation at 12.9 nm. An ideal optic of this typ e should be able to image 0.1-mum features with a contrast exceeding 9 0% at this wavelength. The useful resolution of our ring-field optic i s experimentally found to be approximately 0.2 mum, probably because o f the presence of substrate figuring errors.
