A compact probe based on fiber optics has been developed in order to allow gloss measurements on small samples with a non-homogeneous surface such as photographic negatives. This result has been achieved through a small measurement area, less than 2 mm in diameter, together with the capability of observing a larger area of the sample in order to precisely place the measurement beam. The probe is connected to the light source and the detector system through standard optical fiber patch cables, allowing for a wide range of configurations.
