CHSOS just tested an interferential UV/IR cut filter for Ultraviolet Fluorescence Photography (UVF). This filter is the solution to the auto fluorescence of other UV filters [1]. It is recommended for UVF close up photography. The CHSOS filter set for art examination comprises two filters for UVF photography: XNite CC1 coupled with B+W 420. The first is
Just tested the low-cost mini spectrometer from BWTEK, Quest U (BRC112P-U). This is the most affordable of BWTEK series of mini spectrometers. It features a 2048 pixels linear array and covers the 200 -850 nm range. This test was done in collaboration with MADATEC, an Italian company supplying scientific imaging and analytical equipment also for art conservation
Published on Archeomatica, 1 Marzo 2014 a paper, for Italian readers, introducing the miniaturized spectrometers for Fiber Optics Reflectance Spectroscopy. This paper shows the results of the testing of a FORS (Fiber Optics Reflectance Spectroscopy) system assembled with Ocean Optics components and featuring a USB4000 miniaturized and low cost spectrometer. The small dimensions and little
FORS (Fiber Optics Reflectance Spectroscopy) has been used for art examination and art conservation for at least 2 decades for identification of pigments [1, 2, 3, 4] and dyestuffs [5]. The strength of this method is the relatively simplicity of the equipment: a source of light, a spectrometer and 2 fibers optics, one to deliver
