Spectrophotometers are used in many industries requiring precise colors. Whether we are talking about packaging, paints… this is the essential tool to ensure that the color produced consistently matches the color initially specified. Beyond precision, this clearly promotes waste reduction and saves time and money.

Spectrophotometers analyse the reflected wavelengths of visible polychromatic incident light. The reflected spectrum is measured at a large number of points, at small intervals, and it is compared to a database to deduce the color of the tooth. For an optical measurement, several million reference points are analysed on a tooth. These devices are currently the most precise and are not exposed to problems of aging of the light source.
