Rigaku nano3DX X-ray microscope

The nano3DX, from Rigaku, is a true X-ray microscope (XRM) with the ability to measure relatively large samples at high resolution. The product images the entire sample from multiple angles and can thus reconstruct a 3D image at 0.27 µm resolution. The computer model allows the user to view sections at any point on any plane, providing insights into the structure of the sample.

The product features a high-power rotating anode and high-resolution optics coupled with sub-micron CCD technology. This combination is capable of fast data collection and has the ability to switch anode materials rapidly to optimise data acquisition. Furthermore, the magnification occurs in the detector using true microscope elements.

The geometry of the system allows the sample to be located very close to the high-resolution detector, which provides near-parallel beam optics. This is said to result in improved instrument stability, which prevents smearing, allows for faster data collection times and ultimately yields high resolution.

The primary anode materials used are copper, chromium and molybdenum. The choice of these materials gives the system the flexibility to optimise the X-rays for penetration and contrast based on the atomic weights of materials present in the sample. The product features an ultrawide field of view and is said to measure volumes up to 25 times larger in a single scan compared to other systems at similar resolutions in comparable time frames.

X-ray microscopy is suited to all kinds of materials, from low-density materials such as biological samples to high-density materials such as ceramics and steels, and even materials with low absorption contrast, like CFRPs and pharmaceuticals. The product is suitable for many applications, from materials science to electronics and semiconductors to mining and minerals exploration to life sciences and pharmaceuticals.
