Extended IR spectral response aids art restoration

The use of IR reflectometry to depth profile and visualise the techniques of artists' paintings is well established, but has until now been limited by poor performance at longer wavelengths

Cedip Infrared Systems has published technical data establishing the considerable utility of its Jade SWIR IR camera system for the investigation and visualisation of sub-surface preliminary artwork on paintings.

The use of IR reflectometry to non-destructively depth profile and visualise the primary intentions and techniques of artists' paintings is well established.

However until now most IR cameras have demonstrated poor performance at longer wavelengths beyond 1.7 microns.

Using a advanced 320x240 pixel TE cooled MCT detector array, the Jade SWIR camera provides excellent spectral response from 0.8 to 2.5 microns, with increasing performance towards the longer wavelengths.

The key benefit of the extended spectral responsivity offered by the Jade SWIR is its ability to probe deeper into thick paint layers to reveal sub-surface preliminary artwork not visible below 1.7 microns.
