The Novo-Curve gloss-meter has a very small measurement spot (2mm) that can be used to measure the gloss of very small parts or resolve differences in gloss across small areas.
To get equivalent readings to a standard gloss-meter on surfaces that are slightly irregular it is recommended that the average value is taken of several readings.
These instruments have been used to resolve the gloss differences across holograms, measure the polish on coins, steering wheels and extruded pipe work.
