Paper Abstract

The 1933 LINNIK Point Diffraction Interferometer continues to offer new possibilities in non-contacting aspheric grazing incidence mirror testing. In this work we demonstrate the wave-front aberration of a stigmatic Soft X-Ray reflecting optic recorded at progressively shorter wavelengths to a current limit of 313 nm yielding a twofold increase in sensitivity over previously reported measurements.
