Sigray TriLambda-30 NanoXRM 3D X-Ray Microscope
Highest Resolution 3D X-ray Microscope with Multi-Energy Flexibility
Introducing the Trilambda XRM-30 system: this NanoCT with patented X-ray and optics is designed for ultra-high spatial resolution (35nm) imaging with up to 3 X-ray energies in a single system.
- 3D nano x-ray microscope (nanoXRM) with 35nm resolution
- Highest resolution system on the market. Enabled by x-ray optics.
- Multiple x-ray illumination energies
- Up to three energies selected in a single system for optimised imaging for a broad range of samples (polymers to metals)
- Dual energy nano tomography for quantitative information
- Density and improved contrast can be obtained by taking tomographies at two different energies
The TriLambda nanoXRM achieves over an order of magnitude in superior resolution compared to lensless x-ray microscopes such as the PrismaXRM, which do not use x-ray optics. Such resolution is achieved through the use of Sigray’s proprietary double paraboloidal x-ray optics and diffractive focusing zone plate optics. PrismaXRM and TriLambdaXRM provide natural multi-scale complements to each other; PrismaXRM provides submicron imaging of larger samples, while the TriLambda provides 35-100nm resolution imaging of smaller samples.
Image: Outstanding 35-50nm resolutions can be achieved for x-ray energies ranging from 2.7 keV to 8.04 keV.
Up to three x-ray energies are included in the TriLambda system, providing optimal illumination for the wide range of samples seen in a busy central laboratory. X-ray contrast varies significantly for each x-ray energy, impacting both the time to acquire data and more importantly, the visibility of structures. For example, 5.4 keV is optimal for geological samples (SiO2) but poor for samples with metal in them. For polymers and cells, soft x-ray energies (2.7 keV) provide profound advantages over 8 keV.
Interpreting contrast measurements and CT numbers can be a difficult task when only a single X-ray energy is used for imaging. This is due to the presence of sub-resolution features, such as nanoporosity or nano-scale alloying elements that change the absorption of a sample and lead to errors in image segmentation and inaccurate quantification of the atomic number of a material. By imaging at two different x-ray illumination energies (dual energy), TriLambda removes such errors.

TriLambda’s x-ray source features a patented design in which multiple target materials are in optimal thermal contact with diamond, which has excellent thermal conductivity properties. The rapid cooling of diamond enables higher power loading on the x-ray source to produce an intense beams of x-rays. This thermal benefit enables more materials to be used as x-ray source target materials, each of which produce strong characteristic x-rays of a specific energy. Up to 3 target materials can be customized for the TriLambda-30 source, allowing software selection of the optimal spectra for your sample.

The microstructure of electrodes are increasingly of interest because it is now recognised that damage incurred and agglomeration of particles from charging limits the long-term reliability and lifetime. TriLambdaXRM provides the resolution needed to see these changes – and because of the non-destructive nature of x-rays, can be used to observe such changes over time or in-operando.
Polymers and Biological Samples
A key feature of the TriLambdaXRM is its ability to resolve polymers and biological samples at the nanoscale. Such samples are extremely challenging to image using electron-based techniques due to charging. Using a low “tender” x-ray energy to illuminate the sample at 2.7 keV, TriLambda is able to provide 3D nanoscale biological and polymeric tomographies non-destructively.
