238:), a full field soft X-ray microscope operated by the Center for X-ray Optics and dedicated to various applications in modern nanoscience, such as nanomagnetic materials, environmental and materials sciences and biology. XM-1 uses an X-ray lens to focus X-rays on a CCD, in a manner similar to an optical microscope. XM-1 held the world record in spatial resolution with Fresnel zone plates down to 15 nm and is able to combine high spatial resolution with a sub-100ps time resolution to study e.g. ultrafast spin dynamics. In July 2012, a group at

These microscopes enable the acquisition of soft X-ray tomograms from cryogenically vitrified as well as room temperature samples, employing flat specimen holders such as standard transmission electron microscopy (TEM) grids or glass capillaries.

case of specimens imaged in glass capillaries, the full-tilt tomography may take slightly longer. Resolutions in biological specimens, determined by
Fourier Ring Correlations (1/2 Signal-to-Noise ratio), can achieve 55 nm for two-hour tomograms, with the ability to resolve Siemens star lines and spaces as small as 25 nm.

allows the observation of biological specimens in their hydrated natural state, albeit embedded in water ice. Until now, resolutions of 30 nanometer are possible using the
Fresnel zone plate lens which forms the image using the soft X-rays emitted from a synchrotron. Recently, the use of soft X-rays

The SXT-100 system stands out for its versatility, accommodating a variety of specimen formats. For instance, researchers can acquire tomograms on TEM grids, allowing for ±60 degrees range tilt series collected in 1-degree steps within a time frame ranging from under one hour to two hours. In the

setups offer a compact and easily integratable solution for researchers within laboratory settings. These systems typically utilize laser-driven X-ray sources, with the brightness of the source dependent on the type of target and the power of the laser. Notably, the SXT-100 table-top soft X-ray

The ALS is also home to the world's first soft X-ray microscope designed for biological and biomedical research. This new instrument, XM-2 was designed and built by scientists from the
