Key Advantages:
Nanoscale 35nm Spatial Resolution
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.
Three X-ray Wavelengths (Tri-Lamba) in a Single System
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.
Dual Energy (Dual Contrast)
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.
