NEW: Breakthrough Released November 2023

Key Advantages:

Leading: 300nm (0.3 µm) Spatial Resolution

EclipseXRM is a revolutionary system that bridges the x-ray microscope (XRM) gap between micro-XRM and nano-XRM, offering resolutions below 0.3 µm spatial resolution, even for large samples. This resolution far surpasses that of the leading flexible XRMs on the market, which are limited to ~0.5 µm spatial resolution.

The highest resolution achievable by the system is not only best-in-class, but is also achieved using a highly efficient detection system. This enables much higher throughput when imaging at smaller voxel sizes than other systems on the market.

An example of the EclipseXRM’s resolution advantage over a leading x-ray microscope (XRM) can be easily seen on a shale rock sample (illustrated below). The images from a leading XRM with 0.5 µm spatial resolution using a 20X objective is shown on the left, while the EclipseXRM’s powerful high resolution image is shown on the right hand side. Not only is the EclipseXRM data far markedly crisper (almost SEM-like in sharpness), but the EclipseXRM’s data was also acquired in a fraction of the time (2.5 hours vs. 4 hours). Furthermore, EclipseXRM’s dataset had sufficient signal-to-noise ratio (SNR) for simple FDK (Feldkamp-Davis-Kress) reconstruction, while the leading XRM’s 20X data was reconstructed using time-consuming iterative reconstruction due to poor SNR.

EclipseXRM achieves higher resolution, faster: The same carbonate sample imaged on a leading XRM with two-stage magnification and EclipseXRM. The leading system advertises ~0.5 µm spatial resolution and used a 20X magnification objective to acquire the data in 4 hours, while EclipseXRM acquired 0.3 µm data in <2 hours.
Submicron Resolution, even at Large Working Distances

Large samples and samples in situ typically require larger clearance around the sample for a complete rotation. This can therefore result in poor resolution on standard x-ray systems. One common strategy that has been heavily marketed to address this problem has been to use a “two-stage magnification” scheme using high magnification objective lenses. However, this has trade-offs in detector efficiency.

EclipseXRM’s new, patent-pending architecture offers an alternative to prior approaches, enabling submicron resolution at large working distances without needing high magnification objective lenses (see below).

Novel Multi-Spectral Imaging Enables Maximum Versatility

EclipseXRM was engineered to address the needs of busy central research facilities, encountering a wide variety of sample shapes, sizes, and compositions. These research facilities are often tasked with imaging the samples at the best quality and at the fastest acquisition times. As no single set of components can address the full range, EclipseXRM can incorporate multiple x-ray sources and detectors into a single system. One key option is a Multi-Spectral Source (MSS), which provides unique access to multiple quasi-monochromatic beams of x-rays (unlike the polychromatic x-rays produced by most system’s sources). This provides the outstanding contrast needed for extremely challenging samples, such as low-Z structures in novel lithium battery concepts and biological samples.

EclipseXRM optionally incorporates a Multi-Spectral Source, which produces quasi-monochromatic x-rays for outstanding contrast for challenging samples.

System Features

Novel Architecture: Patent-Pending and Patented X-ray Technology

EclipseXRM was designed by Dr. Wenbing Yun, who has won over four prestigious R&D 100 awards for his x-ray microscope innovations and has pioneered synchrotron and laboratory x-ray microscopes for the past four decades. The system takes advantage of several patent-pending and patented innovations that have been developed by Sigray, as well as the most recent hardware advances such as maintenance-free air-bearing rotary stages with sub-50nm runout and high-efficiency CMOS sensors.

The system has been adopted by some of the leading semiconductor companies and research institutions around the world. (To request a set of complimentary demos on a local system or by Sigray, fill out the form below)

Semiconductor Failure Analysis

3D x-ray microscopy has become the workhorse approach to investigating failures in semiconductor packaging. Due to the ever-decreasing sizes of packaging features, ever-increasing resolution is required to determine failures such as cracks, voids, and delamination. The zoomed-in on a single wire bond shown on the right demonstrates both the superior resolution and contrast of EclipseXRM for semiconductor samples.

Biological and Polymer Samples

Biological and other light samples, such as polmers, can be extremely challenging to image with conventional x-ray techniques, such as microCT, due to their low absorption and ultrahigh resolution needs. EclipseXRM provides both superior contrast and superior resolution to resolve sub-cellular details.

Shown in the example below is a mouse sciatic nerve sample, demonstrating that the system’s ultrahigh resolution clearly details the axons and myelin sheaths.

In-situ Microstructural Evolution

A significant advantage of EclipseXRM’s design is its ability to maintain high submicron resolutions for large samples, enabling high fidelity imaging of samples placed in larger in-situ cells. The system can image 3D microstructural evolution in samples under various conditions, including: heating, cooling, tension and compression (T&C), fluid/gas flow, and more. We will provide robust in-situ solutions for your needs.

Intact Batteries and Batteries in-operando

EclipseXRM provides variable resolution within a sample, allowing hierarchical characterization of batteries – from the full field of view (FOV) to detailed region-of-interest imaging – without the need to de-package the battery. This allows non-destructive identification of problems such as small defects (e.g., cracks, particles) and shorts. EclipseXRM also provides high resolution for detailed information on electrode particles, capturing their shape, size, and the presence of defects (voids, cracks).
