Soft and Hard X-rays X-rays are usually described by their maximum energy, which is determined by the voltage between the electrodes. X-rays with high photon energies (above 5–10 keV) are called hard X-rays, while those with lower energy (and longer wavelength) are called soft X-rays. A photoelectric ionizer utilizes extreme UV to soft X-ray photons to create ions. When the energy of a photon exceeds the ionization potential of the medium it traverses, the photon can create an ion by collision with an atom.

With a wavelength range between 300 eV – 3 keV, soft x-ray microscopes are capable of achieving spatial resolution of several hundred Ångströms (Å). Soft X-rays are generally understood to be X-rays in the energy range of 100-3,000 eV. They have insufficient energy to penetrate the beryllium window of a hard x-ray beamline but have energies higher than that of extreme ultraviolet light.

The first x-ray images above 30 keV have been obtained with the Hard X-ray Telescope on the Yohkoh satellite. The figure below compares the hard x-ray image from one flare with white light and soft x-ray images. The hard x-ray image is similar to the white light image. The soft x-rays, however, come from a more extended region than the hard x-rays. of soft x-raySHG.
