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.
Tricolor filter is composed of
red, green, blue three colors optical glass.
Plate making dichroic mirror has
