then passes through 90 of any infra red light to an infra red absorber 35 reflected light from the sixth cold mirror 32 is directed toward a seventh cold mirror 33 which passes 90 of any remaining infra red light to an infra red absorber 36 the light reflected from the seventh cold mirror 33 surface is directed to an eight cold mirror 34 which passes 90 of any remaining infra red light to an infra red absorber 37 the light reflected from the eighth and final cold mirror 34 is directed out and away from the entire assembly for use by a light concentrator the resulting light output is calculated to contain 53 of the incoming light as shorter wavelength light and 0 0001 of the incoming light as longer wavelength light light emerging from the spf solar photon filter can be sent to a light concentrator for distribution a 1 meter parabolic light concentrator receiving a full 1 meter square area of light would concentrate this light to a level of about 130 db since the concentration includes all light from the spf it is of vital importance that any longer wavelength light having infra red heat generating capability be as minimal as possible with this light equivalent to 0 5 sun of shorter wavelength light with 0 000001 sun of longer wavelength light the resultant distribution light equates to an intensity of over 500 000 suns of short wavelength light while also carrying only 1 sun of infra red light thus the thermal reaction of system components in a distribution system need only tolerate 1 sun of infra red thermal energy.
