... W/ µ In the case of the LX1972A the peak photo response is at 580nm, however depending on the light source, what the human eye perceives as ‘white’ light may actually be composed of peak wavelengths of light other than 520nm. For instance, a typical fluorescent lamp includes dominant light not only near 550nm but also at 404 and 435nm ...
