It is important for microscopy labs and their clients that the performance of SEMs and the quality of the images they create be monitored regularly. Image sharpness, which is related to resolution, is the primary indicator of SEM performance. Based on ISO standards, this SEM Sharpness Measurement Tool is a new feature of Quartz PCI software. It works with a single image or a group of images and can be measured regularly to monitor the performance of a SEM. Detailed reports can be generated in just a few clicks.
