Soft X-Ray MicroscopyEducational Notes

Soft X-ray Microscopy

Soft x-ray microscopy is most commonly used for researching the elemental composition and structure of biological samples. With a wavelength range between 300 eV – 3 keV, soft x-ray microscopes are capable of achieving spatial resolution of several hundred Ångströms (Å).

The primary advantage of soft x-ray microscopy is its ability to form the highest-spatial-resolution images of thick, hydrated biological samples without time-consuming sample preparation required for techniques using electron microscopes. Also, as biological samples mostly comprise of hydrogen, carbon, oxygen, and nitrogen, their primary absorption edges in the water window. Therefore, soft x-ray microscopes provide excellent spectroscopic information and deliver high-contrast images.
