WebWe present an extreme ultraviolet (EUV) microscope using a Schwarzschild objective which is opti-mized for single-shot sub-micrometer imaging of laser-plasma targets. The microscope has been designed and constructed for imaging the scattering from an EUV-heated solid-density hydrogen jet. WebSchwarzschild Objective: Also called "mirror objectives" or "reflecting objectives", these objectives use two parabolic mirrors to collect and focus light. The advantages are a very broad range from the deep UV to the near IR with no chromatic aberration and a long working distance.
