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. 517 $aNew Method to Characterize Degradation of First Surface Aluminum Reflectors 606 $aOptical instruments$xResearch 606 $aSpecular reflectance$xMeasurement 606 $aReflectance 606 $aSolar concentrators$xResearch 615 0$aOptical instruments$xResearch. 615 0$aSpecular reflectance$xMeasurement. 615 0$aReflectance. 615 0$aSolar concentrators$xResearch. 701 $aSutter$b Florian$01423387 712 02$aNational Renewable Energy Laboratory (U.S.) 712 12$aSolarPACES (Conference) 801 0$bSOE 801 1$bSOE 801 2$bGPO 906 $aBOOK 912 $a9910703023203321 996 $aA new method to characterize degradation of first surface aluminum reflectors$93550893 997 $aUNINA
