| 1. A short wavelength compound microscope device comprising:
a condenser zone plate operable to receive short wavelength radiation from a point source and focus the short wavelength radiation
onto a specimen sample;
wherein the sample aligned with an order of diffraction of the condenser zone plate that is greater than one;
and an objective zone plate operable to receive short wavelength radiation that has passed through the specimen sample and
focus the short wavelength radiation onto an imaging device.
