Instrument Introduction:
PMA2133 is a portable device that complies with CIE spectral responseLuminance detectorThe spectral response of this detector is similar to the visual response of the human eye to the illuminated area.
The peak of the spectral luminescence efficiency curve is at 555nm and normalized to 1 at this wavelength. Brightness is the luminous intensity per unit area in a specific direction of illumination. The standard unit for brightness is cd/m2(Candlelight per square meter), another commonly used unit of brightness is fL (feet Lambertian), 1 fL=3.426 cd/m2
