Interference microscope aids surface analysis across industries
GM research labs helped bring the two beam interference microscope to the continent in 1980. The device analyzes micro roughness and depth by splitting light and comparing reflections from a specimen and a flat reference, enabling precise measurements of scratches, peaks, and wear on bearings, cylinders, and other machined parts. The tool also measures plating thickness, tests weathering effects, and standardizes roughness across automotive and aerospace components. It can detect surface variations as small as two thousandths of an inch. The article also notes a Sydney cosmic ray study and a Canada US border distance report.
