CHSOS just added a miniaturized spectrometer to its instrumentation. This system is equivalent to the ones tested already by CHSOS (Ocean Optics, BWTEK) and it will be used for pigments identification following the FORS (Fiber Optics Reflectance Spectroscopy) method. CHSOS chose a ASEQ LR1 spectrometer (300-1000 nm, 2nm resolution with 100um slit) This spectrometer weights just 430 gr and
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
A new free online FORS spectra database of pigments is available. FORS (Fiber Optics Reflectance Spectroscopy) is a low-cost spectroscopy and it is used to identify pigments on art works. CHSOS tested an innovative miniaturized and affordable spectrometer and created the spectral database. This new paper “FORS spectral database of historical pigments in different binders” introduces
