Near-UV to mid-IR reflectance imaging spectroscopy of paintings on the macroscale.Broad spectral range reflectance imaging spectroscopy (BR-RIS) from the near UV through the mid-infrared (IR) (350 to 25,000 nm or 28,571 to 400 cm-1) was investigated as an imaging modality to provide maps of organic and inorganic artists' materials in paintings.  To test BR-RIS, image cubes from early Italian Renaissance illuminated manuscripts were acquired using two spectrometers.  BR-RIS has a more straightforward analysis approach as implemented here than visible-to-NIR, mid-IR, or XRF imaging spectroscopy alone and offers the largest amount of macroscale information for mapping artists' materials by comparison.
