A soft x-ray microscope (E{approx_lt}3keV) with high spatial resolution ({approximately}3{mu}m) has been characterized at the University of Rochester{close_quote}s Laboratory for Laser Energetics and used for initial experiments on the Omega laser system [Boehly {ital et al.}, Opt. Commun. {bold 133}, 495 (1997)] to study the hydrodynamic stability of directly driven planar foils. The microscope, which is an optimized Kirkpatrick{endash}Baez-type design, is used to obtain four x-ray radiographs of laser-driven foils. Time-resolved images are obtained with either custom-built framing cameras (time resolution {approximately}80ps) or by using short-pulse backlighter beams ({Delta}t{approx_lt}200ps). In the former case, a spatial resolution of {approximately}7{mu}m was obtained (limited by the framing camera), while in the latter case a resolution of {approximately}3{mu}m was obtained. This paper details the testing, calibration, and initial use of this microscope in the laboratory and on Omega. {copyright} {ital 1998 American Institute of Physics.}
