ISO 25387:2026 – Measuring Point Resolution in High-Resolution Electron Microscopy

Microbeam analysis — Analytical electron microscopy — Procedures for determining the point resolution of high-resolution transmission electron microscope

High-resolution transmission electron microscopy (HRTEM) is a cornerstone tool for characterizing nanoscale materials with atomic-level detail. The critical metric of HRTEM performance is its point resolution (Scherzer resolution), directly impacting the ability to image and analyze the smallest features in materials science, semiconductors, and life sciences. ISO 25387:2026 defines universal procedures for determining this crucial metric and the spherical aberration coefficient of the objective lens.

What does the standard cover?

• Details a process for determining Scherzer resolution using FFT analysis of images from amorphous thin films.
• Specifies how to identify and measure at least three dark rings in FFT patterns, calibrate spatial frequency axes, and calculate the real spherical aberration coefficient of the microscope.
