The device measures the specular reflectance at three acceptance angles and the wavelengths with spatial resolution using a digital camera's CMOS sensor. It can be used to measure the corrosion growth rate during outdoor and accelerated exposure tests. These results will allow a correlation between the degraded mirror surface and its specular reflectance.New Method to Characterize Degradation of First Surface Aluminum Reflectors Optical instrumentsResearchSpecular reflectanceMeasurementReflectanceSolar concentratorsResearchOptical instrumentsResearch.Specular reflectanceMeasurement.Reflectance.Solar concentratorsResearch.Sutter Florian1423387National Renewable Energy Laboratory (U.S.)SolarPACES (Conference)SOESOEGPOBOOK9910703023203321A new method to characterize degradation of first surface aluminum reflectors3550893UNINA
