Standard Practice for Calibrating the Magnification of a Scanning Electron Microscopedoi:ASTM E766-981.1本规程旨在使用国家标准与技术研究所(NIST)校准样品标准参考材料(SRM)484校准扫描电子显微镜(SEM)的放大率.由于在不同的放大倍数下,SEM读数上显示的真实放大倍数和放大倍数之间的关系可能不同,因此必须将此实践...
of the lens) is real, and it appears on the side of the lens opposite the one on which the object is present. On the other hand, a virtual image occurs when the prolongations of the light rays converge to form an image, but the light rays themselves do not reach the point of ...
A combination of drift distortion removal and spatial distortion removal are performed to correct Scanning Electron Microscope (SEM) images at both ×200 and ×10,000 magnification. Using multiple, time-spaced images and in-plane rigid body motions to extract the relative displacement field throughout...
Measurements are made by a special SEM where each individual pattern is measured. Other CRM’s may calibrate using optical diffraction. This technique averages over large patterned areas, it does not measure individual "pitches" – like your microscope. Test Method: (in compliance with ISO/IEC...
Regardless of whether you are an academic researcher or industrial laboratory specialist, all scanning electron microscope (SEM) operators are confronted by their scale bar at some point. The burning question is usually something like, “How do I know this scale bar is accurate?” Mak breaks down...

that is the tendency of the replica film (or any TEM sample for that matter) to "sag" as it is stretched across the grid opening. This sag becomes more pronounced as the hole size becomes larger (e.g. smaller number of the grid mesh size). One can minimize the grid sag by requestin...

Traditionally these types of standards have been calibrated at the National Physical Laboratory using optical microscopes, SPMs, or SEMs incorporating scanning stages fitted with laser interferometers. Displacing and monitoring the position of the stage under a microscope enables precision length measurements...
