Photoelectricity absorber
measures the progress and the degree of illumination
of the light, in order to that the Luminosity
function of the absorber is the same to the Luminosity
function of human eye, must perform to revise.
Luminosity function revision glass
is uses for revising the photoelectricity receiver
(for example selenium, silicon photocell, photoelectric
cell) regards with the human Luminosity function
the difference, each kind of different photoelectricity
receiver should apply different revision glass.
