Light micrograph of a longitudinal section through a cello D string. This is a perlon based cello string where the central perlon filament (blue) has a copper wire and then a flattened chrome steel ribbon wound around it. A short section of the cello string was embedded in light curing resin and then ground and diamond polished to match the middle of the longitudinal oriented string. Microscopic contrast technique: Incident differential interference contrast. Magnification 40x when printed 10 centimetres wide. | |
