Transmission Electron Micrograph of diffraction grating,an optical device consisting of a glass plate or a mirror with a large number of equidistant parallel lines or grooves on its surface; it is used to disperse a beam of light (or other electromagnetic radiation) into wavelengths to produce a spectrum. This has a spacing of 462.9nm,2160 lines per millimetre onto 3.05mm grid,ideal for calibration electron-optical magnification up to the x80000/100000 range. Carbon replica shadowed with germanium; on 200 mesh,3.05 mm grid | |
