It plays a crucial role in conservation efforts by providing Abstract: Infrared Reflectography (IR) is a non-destructiv e technique used for the analysis of artworks (paintings) to reveal hidden particularities under the pictorial layer. Scarcely ever, mainly because of higher costs, solid state detector cameras operating up to 1. FLIR is the world leader in the design, manufacture, and marketing of thermal imaging infrared cameras. To obtain high-resolution images with the modified DSLR, a Infrared Reflectography (IRR) was performed with an InGaAs camera (320x256pixels) Merlin NIR by Indigo Systems using the same Nikon Nikkor 50mm f/1. To get the optimum resolution from the camera, it’s important to set it at the right distance for your object. As a result, paintings or illuminations must often be recorded in small areas and the images joined together to give a full picture (called an infrared reflectogram mosaic). To obtain high-resolution images with the modified DSLR, a To acquire the images, radiation sources, ranging from ultraviolet to near infrared, were used; analyses of ultraviolet fluorescence (UVF), infrared reflectography (IRR), infrared false colors The Xenics Brand specializes in designing and marketing infrared sensors, cores and cameras that deliver unparalleled Electro-Optical performance and functionalities.
