Summary

Description
English: Scanning electron microscopes are capable of an extremely wide range of magnifications hard to visualise with a simple image, instead this video shows a zoom in from a typical low magnification to a high magnification. It starts at 25x, about 6 mm across the whole field of view, and zooms in to 12000x, about 12 μm across the whole field of view. The spherical objects are glass beads with a diameter of 10 μm, similar in diameter to a red blood cell. This video was generated from a series of 10 images at different magnifications; 25, 50, 100, 200, 400, 800, 1600, 3300, 6500 and 12000x. The speed of the video is such that every two seconds the magnification doubles.
