Abstract

In the present work, a new imaging device for multi spectral analysis in the visible range is presented, together with its own performances and an example of its application. The instruments can be used to acquire photometric and colorimetric characteristics of wide surfaces in quick and easy way. It is composed by a scientific grade CCD camera and a tunable narrow band filter bench; it acts as a spectroradiometer with a high spatial resolution and a spectral resolution, depending on the bandwidth of the filters. Its application as monitoring device is presented; it is the case of the colour fading analysis of an art print undergone a light forced exposure.
