Unity BEX imaging detector

Traditional imaging modeSlow speed, insufficient information content

Until now, conventionalSEM uses secondary electron or backscattered electron signals to present a gray white contrast image, showing the appearance of sample undulations or atomic number differences. Without imaging information of elements, searching for regions of interest based solely on morphology is often time-consuming and labor-intensive.

BEX: Integrating high speed and strength

The Unity detector is placed under the polar shoe, with high solid angle and dual sensors, and can quickly collect colored BEX signals. It can even achieve fast BEX imaging at lower beam currents, and is insensitive to sample fluctuations, with almost no shadow effect.

Imaging mode based on element distribution

The Unity detector can quickly and efficiently locate the area of interest in the sample, and the process of browsing the sample is the process of high-resolution BEX imaging, presenting the distribution of elements in real time. In an instant, a comprehensive understanding of the sample can be obtained, and based on the AZtec platform, EDS, WDS, or EBSD can be switched with just one click for more in-depth analysis.

The Importance of BEX

BEX imaging and panoramic mode can improve detection efficiency by more than a hundred times. In the future, more samples can be detected and more analysis results can be obtained at the same time, which is a beneficial tool that cannot be separated from scientific research and production.

Traditional workflow

Searching for abnormal areas in a sample is usually time-consuming, labor-intensive, and requires repeated inspections. It is tedious, tedious, and heavily dependent on the operator's perception or familiarity with the sample. It usually requires multiple repetitions to determine the area that needs to be analyzed. Due to the inability to collect data during the retrieval process, it cannot be guaranteed that abnormal areas will be detected in a timely manner.

BEX workflow

useUnity detector, with more dynamic analysis, can obtain richer data. The use of BEX's imaging and panoramic modes eliminates the need for subjective guessing by operators. With these valuable stored data, based on rigorous analysis, it is possible to search for anomalies and areas of interest more reliably and rigorously.
