How does PIN-10AP relate to C.I.E. curve?
PIN-10AP is a detector / filter combination with a spectral response matching the CIE photopic spectrum. This detector is designed to have a spectral response like that of the human eye’s visual response in the photopic region. This is the response of the eye with impinging intensities greater than about 0.1 Lux. In this region the eye response peaks at 555nm.
