31 May 2011: Dr Simon Alcock from the Optics and Metrology Group inspecting the Diamond-NOM (Nanometre Optical Measurements), a world-class metrology tool developed by Diamond in collaboration with the HZB/BESSY synchrotron, Berlin. The Diamond-NOM is designed to characterise the surface of synchrotron mirrors, and operates by scanning a narrow beam of light across the mirror’s surface and recording the angle of deflection using an autocollimator. It can routinely measure the angle (approximately a millionth of a degree) subtended by the width of a human hair at a distance of five kilometres! Zoom
